-core.fileMode::
-	Tells Git if the executable bit of files in the working tree
-	is to be honored.
-+
-Some filesystems lose the executable bit when a file that is
-marked as executable is checked out, or checks out a
-non-executable file with executable bit on.
-linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
-to see if it handles the executable bit correctly
-and this variable is automatically set as necessary.
-+
-A repository, however, may be on a filesystem that handles
-the filemode correctly, and this variable is set to 'true'
-when created, but later may be made accessible from another
-environment that loses the filemode (e.g. exporting ext4 via
-CIFS mount, visiting a Cygwin created repository with
-Git for Windows or Eclipse).
-In such a case it may be necessary to set this variable to 'false'.
-See linkgit:git-update-index[1].
-+
-The default is true (when core.filemode is not specified in the config file).
-
-core.hideDotFiles::
-	(Windows-only) If true, mark newly-created directories and files whose
-	name starts with a dot as hidden.  If 'dotGitOnly', only the `.git/`
-	directory is hidden, but no other files starting with a dot.  The
-	default mode is 'dotGitOnly'.
-
-core.ignoreCase::
-	Internal variable which enables various workarounds to enable
-	Git to work better on filesystems that are not case sensitive,
-	like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
-	finds "makefile" when Git expects "Makefile", Git will assume
-	it is really the same file, and continue to remember it as
-	"Makefile".
-+
-The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
-will probe and set core.ignoreCase true if appropriate when the repository
-is created.
-+
-Git relies on the proper configuration of this variable for your operating
-and file system. Modifying this value may result in unexpected behavior.
-
-core.precomposeUnicode::
-	This option is only used by Mac OS implementation of Git.
-	When core.precomposeUnicode=true, Git reverts the unicode decomposition
-	of filenames done by Mac OS. This is useful when sharing a repository
-	between Mac OS and Linux or Windows.
-	(Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
-	When false, file names are handled fully transparent by Git,
-	which is backward compatible with older versions of Git.
-
-core.protectHFS::
-	If set to true, do not allow checkout of paths that would
-	be considered equivalent to `.git` on an HFS+ filesystem.
-	Defaults to `true` on Mac OS, and `false` elsewhere.
-
-core.protectNTFS::
-	If set to true, do not allow checkout of paths that would
-	cause problems with the NTFS filesystem, e.g. conflict with
-	8.3 "short" names.
-	Defaults to `true` on Windows, and `false` elsewhere.
-
-core.fsmonitor::
-	If set, the value of this variable is used as a command which
-	will identify all files that may have changed since the
-	requested date/time. This information is used to speed up git by
-	avoiding unnecessary processing of files that have not changed.
-	See the "fsmonitor-watchman" section of linkgit:githooks[5].
-
-core.trustctime::
-	If false, the ctime differences between the index and the
-	working tree are ignored; useful when the inode change time
-	is regularly modified by something outside Git (file system
-	crawlers and some backup systems).
-	See linkgit:git-update-index[1]. True by default.
-
-core.splitIndex::
-	If true, the split-index feature of the index will be used.
-	See linkgit:git-update-index[1]. False by default.
-
-core.untrackedCache::
-	Determines what to do about the untracked cache feature of the
-	index. It will be kept, if this variable is unset or set to
-	`keep`. It will automatically be added if set to `true`. And
-	it will automatically be removed, if set to `false`. Before
-	setting it to `true`, you should check that mtime is working
-	properly on your system.
-	See linkgit:git-update-index[1]. `keep` by default.
-
-core.checkStat::
-	When missing or is set to `default`, many fields in the stat
-	structure are checked to detect if a file has been modified
-	since Git looked at it.  When this configuration variable is
-	set to `minimal`, sub-second part of mtime and ctime, the
-	uid and gid of the owner of the file, the inode number (and
-	the device number, if Git was compiled to use it), are
-	excluded from the check among these fields, leaving only the
-	whole-second part of mtime (and ctime, if `core.trustCtime`
-	is set) and the filesize to be checked.
-+
-There are implementations of Git that do not leave usable values in
-some fields (e.g. JGit); by excluding these fields from the
-comparison, the `minimal` mode may help interoperability when the
-same repository is used by these other systems at the same time.
-
-core.quotePath::
-	Commands that output paths (e.g. 'ls-files', 'diff'), will
-	quote "unusual" characters in the pathname by enclosing the
-	pathname in double-quotes and escaping those characters with
-	backslashes in the same way C escapes control characters (e.g.
-	`\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
-	values larger than 0x80 (e.g. octal `\302\265` for "micro" in
-	UTF-8).  If this variable is set to false, bytes higher than
-	0x80 are not considered "unusual" any more. Double-quotes,
-	backslash and control characters are always escaped regardless
-	of the setting of this variable.  A simple space character is
-	not considered "unusual".  Many commands can output pathnames
-	completely verbatim using the `-z` option. The default value
-	is true.
-
-core.eol::
-	Sets the line ending type to use in the working directory for
-	files that have the `text` property set when core.autocrlf is false.
-	Alternatives are 'lf', 'crlf' and 'native', which uses the platform's
-	native line ending.  The default value is `native`.  See
-	linkgit:gitattributes[5] for more information on end-of-line
-	conversion.
-
-core.safecrlf::
-	If true, makes Git check if converting `CRLF` is reversible when
-	end-of-line conversion is active.  Git will verify if a command
-	modifies a file in the work tree either directly or indirectly.
-	For example, committing a file followed by checking out the
-	same file should yield the original file in the work tree.  If
-	this is not the case for the current setting of
-	`core.autocrlf`, Git will reject the file.  The variable can
-	be set to "warn", in which case Git will only warn about an
-	irreversible conversion but continue the operation.
-+
-CRLF conversion bears a slight chance of corrupting data.
-When it is enabled, Git will convert CRLF to LF during commit and LF to
-CRLF during checkout.  A file that contains a mixture of LF and
-CRLF before the commit cannot be recreated by Git.  For text
-files this is the right thing to do: it corrects line endings
-such that we have only LF line endings in the repository.
-But for binary files that are accidentally classified as text the
-conversion can corrupt data.
-+
-If you recognize such corruption early you can easily fix it by
-setting the conversion type explicitly in .gitattributes.  Right
-after committing you still have the original file in your work
-tree and this file is not yet corrupted.  You can explicitly tell
-Git that this file is binary and Git will handle the file
-appropriately.
-+
-Unfortunately, the desired effect of cleaning up text files with
-mixed line endings and the undesired effect of corrupting binary
-files cannot be distinguished.  In both cases CRLFs are removed
-in an irreversible way.  For text files this is the right thing
-to do because CRLFs are line endings, while for binary files
-converting CRLFs corrupts data.
-+
-Note, this safety check does not mean that a checkout will generate a
-file identical to the original file for a different setting of
-`core.eol` and `core.autocrlf`, but only for the current one.  For
-example, a text file with `LF` would be accepted with `core.eol=lf`
-and could later be checked out with `core.eol=crlf`, in which case the
-resulting file would contain `CRLF`, although the original file
-contained `LF`.  However, in both work trees the line endings would be
-consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
-file with mixed line endings would be reported by the `core.safecrlf`
-mechanism.
-
-core.autocrlf::
-	Setting this variable to "true" is the same as setting
-	the `text` attribute to "auto" on all files and core.eol to "crlf".
-	Set to true if you want to have `CRLF` line endings in your
-	working directory and the repository has LF line endings.
-	This variable can be set to 'input',
-	in which case no output conversion is performed.
-
-core.checkRoundtripEncoding::
-	A comma and/or whitespace separated list of encodings that Git
-	performs UTF-8 round trip checks on if they are used in an
-	`working-tree-encoding` attribute (see linkgit:gitattributes[5]).
-	The default value is `SHIFT-JIS`.
-
-core.symlinks::
-	If false, symbolic links are checked out as small plain files that
-	contain the link text. linkgit:git-update-index[1] and
-	linkgit:git-add[1] will not change the recorded type to regular
-	file. Useful on filesystems like FAT that do not support
-	symbolic links.
-+
-The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
-will probe and set core.symlinks false if appropriate when the repository
-is created.
-
-core.gitProxy::
-	A "proxy command" to execute (as 'command host port') instead
-	of establishing direct connection to the remote server when
-	using the Git protocol for fetching. If the variable value is
-	in the "COMMAND for DOMAIN" format, the command is applied only
-	on hostnames ending with the specified domain string. This variable
-	may be set multiple times and is matched in the given order;
-	the first match wins.
-+
-Can be overridden by the `GIT_PROXY_COMMAND` environment variable
-(which always applies universally, without the special "for"
-handling).
-+
-The special string `none` can be used as the proxy command to
-specify that no proxy be used for a given domain pattern.
-This is useful for excluding servers inside a firewall from
-proxy use, while defaulting to a common proxy for external domains.
-
-core.sshCommand::
-	If this variable is set, `git fetch` and `git push` will
-	use the specified command instead of `ssh` when they need to
-	connect to a remote system. The command is in the same form as
-	the `GIT_SSH_COMMAND` environment variable and is overridden
-	when the environment variable is set.
-
-core.ignoreStat::
-	If true, Git will avoid using lstat() calls to detect if files have
-	changed by setting the "assume-unchanged" bit for those tracked files
-	which it has updated identically in both the index and working tree.
-+
-When files are modified outside of Git, the user will need to stage
-the modified files explicitly (e.g. see 'Examples' section in
-linkgit:git-update-index[1]).
-Git will not normally detect changes to those files.
-+
-This is useful on systems where lstat() calls are very slow, such as
-CIFS/Microsoft Windows.
-+
-False by default.
-
-core.preferSymlinkRefs::
-	Instead of the default "symref" format for HEAD
-	and other symbolic reference files, use symbolic links.
-	This is sometimes needed to work with old scripts that
-	expect HEAD to be a symbolic link.
-
-core.alternateRefsCommand::
-	When advertising tips of available history from an alternate, use the shell to
-	execute the specified command instead of linkgit:git-for-each-ref[1]. The
-	first argument is the absolute path of the alternate. Output must contain one
-	hex object id per line (i.e., the same as produce by `git for-each-ref
-	--format='%(objectname)'`).
-+
-Note that you cannot generally put `git for-each-ref` directly into the config
-value, as it does not take a repository path as an argument (but you can wrap
-the command above in a shell script).
-
-core.alternateRefsPrefixes::
-	When listing references from an alternate, list only references that begin
-	with the given prefix. Prefixes match as if they were given as arguments to
-	linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with
-	whitespace. If `core.alternateRefsCommand` is set, setting
-	`core.alternateRefsPrefixes` has no effect.
-
-core.bare::
-	If true this repository is assumed to be 'bare' and has no
-	working directory associated with it.  If this is the case a
-	number of commands that require a working directory will be
-	disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
-+
-This setting is automatically guessed by linkgit:git-clone[1] or
-linkgit:git-init[1] when the repository was created.  By default a
-repository that ends in "/.git" is assumed to be not bare (bare =
-false), while all other repositories are assumed to be bare (bare
-= true).
-
-core.worktree::
-	Set the path to the root of the working tree.
-	If `GIT_COMMON_DIR` environment variable is set, core.worktree
-	is ignored and not used for determining the root of working tree.
-	This can be overridden by the `GIT_WORK_TREE` environment
-	variable and the `--work-tree` command-line option.
-	The value can be an absolute path or relative to the path to
-	the .git directory, which is either specified by --git-dir
-	or GIT_DIR, or automatically discovered.
-	If --git-dir or GIT_DIR is specified but none of
-	--work-tree, GIT_WORK_TREE and core.worktree is specified,
-	the current working directory is regarded as the top level
-	of your working tree.
-+
-Note that this variable is honored even when set in a configuration
-file in a ".git" subdirectory of a directory and its value differs
-from the latter directory (e.g. "/path/to/.git/config" has
-core.worktree set to "/different/path"), which is most likely a
-misconfiguration.  Running Git commands in the "/path/to" directory will
-still use "/different/path" as the root of the work tree and can cause
-confusion unless you know what you are doing (e.g. you are creating a
-read-only snapshot of the same index to a location different from the
-repository's usual working tree).
-
-core.logAllRefUpdates::
-	Enable the reflog. Updates to a ref <ref> is logged to the file
-	"`$GIT_DIR/logs/<ref>`", by appending the new and old
-	SHA-1, the date/time and the reason of the update, but
-	only when the file exists.  If this configuration
-	variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
-	file is automatically created for branch heads (i.e. under
-	`refs/heads/`), remote refs (i.e. under `refs/remotes/`),
-	note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
-	If it is set to `always`, then a missing reflog is automatically
-	created for any ref under `refs/`.
-+
-This information can be used to determine what commit
-was the tip of a branch "2 days ago".
-+
-This value is true by default in a repository that has
-a working directory associated with it, and false by
-default in a bare repository.
-
-core.repositoryFormatVersion::
-	Internal variable identifying the repository format and layout
-	version.
-
-core.sharedRepository::
-	When 'group' (or 'true'), the repository is made shareable between
-	several users in a group (making sure all the files and objects are
-	group-writable). When 'all' (or 'world' or 'everybody'), the
-	repository will be readable by all users, additionally to being
-	group-shareable. When 'umask' (or 'false'), Git will use permissions
-	reported by umask(2). When '0xxx', where '0xxx' is an octal number,
-	files in the repository will have this mode value. '0xxx' will override
-	user's umask value (whereas the other options will only override
-	requested parts of the user's umask value). Examples: '0660' will make
-	the repo read/write-able for the owner and group, but inaccessible to
-	others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
-	repository that is group-readable but not group-writable.
-	See linkgit:git-init[1]. False by default.
-
-core.warnAmbiguousRefs::
-	If true, Git will warn you if the ref name you passed it is ambiguous
-	and might match multiple refs in the repository. True by default.
-
-core.compression::
-	An integer -1..9, indicating a default compression level.
-	-1 is the zlib default. 0 means no compression,
-	and 1..9 are various speed/size tradeoffs, 9 being slowest.
-	If set, this provides a default to other compression variables,
-	such as `core.looseCompression` and `pack.compression`.
-
-core.looseCompression::
-	An integer -1..9, indicating the compression level for objects that
-	are not in a pack file. -1 is the zlib default. 0 means no
-	compression, and 1..9 are various speed/size tradeoffs, 9 being
-	slowest.  If not set,  defaults to core.compression.  If that is
-	not set,  defaults to 1 (best speed).
-
-core.packedGitWindowSize::
-	Number of bytes of a pack file to map into memory in a
-	single mapping operation.  Larger window sizes may allow
-	your system to process a smaller number of large pack files
-	more quickly.  Smaller window sizes will negatively affect
-	performance due to increased calls to the operating system's
-	memory manager, but may improve performance when accessing
-	a large number of large pack files.
-+
-Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
-MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
-be reasonable for all users/operating systems.  You probably do
-not need to adjust this value.
-+
-Common unit suffixes of 'k', 'm', or 'g' are supported.
-
-core.packedGitLimit::
-	Maximum number of bytes to map simultaneously into memory
-	from pack files.  If Git needs to access more than this many
-	bytes at once to complete an operation it will unmap existing
-	regions to reclaim virtual address space within the process.
-+
-Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
-unlimited) on 64 bit platforms.
-This should be reasonable for all users/operating systems, except on
-the largest projects.  You probably do not need to adjust this value.
-+
-Common unit suffixes of 'k', 'm', or 'g' are supported.
-
-core.deltaBaseCacheLimit::
-	Maximum number of bytes to reserve for caching base objects
-	that may be referenced by multiple deltified objects.  By storing the
-	entire decompressed base objects in a cache Git is able
-	to avoid unpacking and decompressing frequently used base
-	objects multiple times.
-+
-Default is 96 MiB on all platforms.  This should be reasonable
-for all users/operating systems, except on the largest projects.
-You probably do not need to adjust this value.
-+
-Common unit suffixes of 'k', 'm', or 'g' are supported.
-
-core.bigFileThreshold::
-	Files larger than this size are stored deflated, without
-	attempting delta compression.  Storing large files without
-	delta compression avoids excessive memory usage, at the
-	slight expense of increased disk usage. Additionally files
-	larger than this size are always treated as binary.
-+
-Default is 512 MiB on all platforms.  This should be reasonable
-for most projects as source code and other text files can still
-be delta compressed, but larger binary media files won't be.
-+
-Common unit suffixes of 'k', 'm', or 'g' are supported.
-
-core.excludesFile::
-	Specifies the pathname to the file that contains patterns to
-	describe paths that are not meant to be tracked, in addition
-	to '.gitignore' (per-directory) and '.git/info/exclude'.
-	Defaults to `$XDG_CONFIG_HOME/git/ignore`.
-	If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
-	is used instead. See linkgit:gitignore[5].
-
-core.askPass::
-	Some commands (e.g. svn and http interfaces) that interactively
-	ask for a password can be told to use an external program given
-	via the value of this variable. Can be overridden by the `GIT_ASKPASS`
-	environment variable. If not set, fall back to the value of the
-	`SSH_ASKPASS` environment variable or, failing that, a simple password
-	prompt. The external program shall be given a suitable prompt as
-	command-line argument and write the password on its STDOUT.
-
-core.attributesFile::
-	In addition to '.gitattributes' (per-directory) and
-	'.git/info/attributes', Git looks into this file for attributes
-	(see linkgit:gitattributes[5]). Path expansions are made the same
-	way as for `core.excludesFile`. Its default value is
-	`$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
-	set or empty, `$HOME/.config/git/attributes` is used instead.
-
-core.hooksPath::
-	By default Git will look for your hooks in the
-	'$GIT_DIR/hooks' directory. Set this to different path,
-	e.g. '/etc/git/hooks', and Git will try to find your hooks in
-	that directory, e.g. '/etc/git/hooks/pre-receive' instead of
-	in '$GIT_DIR/hooks/pre-receive'.
-+
-The path can be either absolute or relative. A relative path is
-taken as relative to the directory where the hooks are run (see
-the "DESCRIPTION" section of linkgit:githooks[5]).
-+
-This configuration variable is useful in cases where you'd like to
-centrally configure your Git hooks instead of configuring them on a
-per-repository basis, or as a more flexible and centralized
-alternative to having an `init.templateDir` where you've changed
-default hooks.
-
-core.editor::
-	Commands such as `commit` and `tag` that let you edit
-	messages by launching an editor use the value of this
-	variable when it is set, and the environment variable
-	`GIT_EDITOR` is not set.  See linkgit:git-var[1].
-
-core.commentChar::
-	Commands such as `commit` and `tag` that let you edit
-	messages consider a line that begins with this character
-	commented, and removes them after the editor returns
-	(default '#').
-+
-If set to "auto", `git-commit` would select a character that is not
-the beginning character of any line in existing commit messages.
-
-core.filesRefLockTimeout::
-	The length of time, in milliseconds, to retry when trying to
-	lock an individual reference. Value 0 means not to retry at
-	all; -1 means to try indefinitely. Default is 100 (i.e.,
-	retry for 100ms).
-
-core.packedRefsTimeout::
-	The length of time, in milliseconds, to retry when trying to
-	lock the `packed-refs` file. Value 0 means not to retry at
-	all; -1 means to try indefinitely. Default is 1000 (i.e.,
-	retry for 1 second).
-
-core.pager::
-	Text viewer for use by Git commands (e.g., 'less').  The value
-	is meant to be interpreted by the shell.  The order of preference
-	is the `$GIT_PAGER` environment variable, then `core.pager`
-	configuration, then `$PAGER`, and then the default chosen at
-	compile time (usually 'less').
-+
-When the `LESS` environment variable is unset, Git sets it to `FRX`
-(if `LESS` environment variable is set, Git does not change it at
-all).  If you want to selectively override Git's default setting
-for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
-be passed to the shell by Git, which will translate the final
-command to `LESS=FRX less -S`. The environment does not set the
-`S` option but the command line does, instructing less to truncate
-long lines. Similarly, setting `core.pager` to `less -+F` will
-deactivate the `F` option specified by the environment from the
-command-line, deactivating the "quit if one screen" behavior of
-`less`.  One can specifically activate some flags for particular
-commands: for example, setting `pager.blame` to `less -S` enables
-line truncation only for `git blame`.
-+
-Likewise, when the `LV` environment variable is unset, Git sets it
-to `-c`.  You can override this setting by exporting `LV` with
-another value or setting `core.pager` to `lv +c`.
-
-core.whitespace::
-	A comma separated list of common whitespace problems to
-	notice.  'git diff' will use `color.diff.whitespace` to
-	highlight them, and 'git apply --whitespace=error' will
-	consider them as errors.  You can prefix `-` to disable
-	any of them (e.g. `-trailing-space`):
-+
-* `blank-at-eol` treats trailing whitespaces at the end of the line
-  as an error (enabled by default).
-* `space-before-tab` treats a space character that appears immediately
-  before a tab character in the initial indent part of the line as an
-  error (enabled by default).
-* `indent-with-non-tab` treats a line that is indented with space
-  characters instead of the equivalent tabs as an error (not enabled by
-  default).
-* `tab-in-indent` treats a tab character in the initial indent part of
-  the line as an error (not enabled by default).
-* `blank-at-eof` treats blank lines added at the end of file as an error
-  (enabled by default).
-* `trailing-space` is a short-hand to cover both `blank-at-eol` and
-  `blank-at-eof`.
-* `cr-at-eol` treats a carriage-return at the end of line as
-  part of the line terminator, i.e. with it, `trailing-space`
-  does not trigger if the character before such a carriage-return
-  is not a whitespace (not enabled by default).
-* `tabwidth=<n>` tells how many character positions a tab occupies; this
-  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
-  errors. The default tab width is 8. Allowed values are 1 to 63.
-
-core.fsyncObjectFiles::
-	This boolean will enable 'fsync()' when writing object files.
-+
-This is a total waste of time and effort on a filesystem that orders
-data writes properly, but can be useful for filesystems that do not use
-journalling (traditional UNIX filesystems) or that only journal metadata
-and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
-
-core.preloadIndex::
-	Enable parallel index preload for operations like 'git diff'
-+
-This can speed up operations like 'git diff' and 'git status' especially
-on filesystems like NFS that have weak caching semantics and thus
-relatively high IO latencies.  When enabled, Git will do the
-index comparison to the filesystem data in parallel, allowing
-overlapping IO's.  Defaults to true.
-
-core.createObject::
-	You can set this to 'link', in which case a hardlink followed by
-	a delete of the source are used to make sure that object creation
-	will not overwrite existing objects.
-+
-On some file system/operating system combinations, this is unreliable.
-Set this config setting to 'rename' there; However, This will remove the
-check that makes sure that existing object files will not get overwritten.
-
-core.notesRef::
-	When showing commit messages, also show notes which are stored in
-	the given ref.  The ref must be fully qualified.  If the given
-	ref does not exist, it is not an error but means that no
-	notes should be printed.
-+
-This setting defaults to "refs/notes/commits", and it can be overridden by
-the `GIT_NOTES_REF` environment variable.  See linkgit:git-notes[1].
-
-core.commitGraph::
-	If true, then git will read the commit-graph file (if it exists)
-	to parse the graph structure of commits. Defaults to false. See
-	linkgit:git-commit-graph[1] for more information.
-
-core.useReplaceRefs::
-	If set to `false`, behave as if the `--no-replace-objects`
-	option was given on the command line. See linkgit:git[1] and
-	linkgit:git-replace[1] for more information.
-
-core.multiPackIndex::
-	Use the multi-pack-index file to track multiple packfiles using a
-	single index. See link:technical/multi-pack-index.html[the
-	multi-pack-index design document].
-
-core.sparseCheckout::
-	Enable "sparse checkout" feature. See section "Sparse checkout" in
-	linkgit:git-read-tree[1] for more information.
-
-core.abbrev::
-	Set the length object names are abbreviated to.  If
-	unspecified or set to "auto", an appropriate value is
-	computed based on the approximate number of packed objects
-	in your repository, which hopefully is enough for
-	abbreviated object names to stay unique for some time.
-	The minimum length is 4.

+core.fileMode::
+	Tells Git if the executable bit of files in the working tree
+	is to be honored.
++
+Some filesystems lose the executable bit when a file that is
+marked as executable is checked out, or checks out a
+non-executable file with executable bit on.
+linkgit:git-clone[1] or linkgit:git-init[1] probe the filesystem
+to see if it handles the executable bit correctly
+and this variable is automatically set as necessary.
++
+A repository, however, may be on a filesystem that handles
+the filemode correctly, and this variable is set to 'true'
+when created, but later may be made accessible from another
+environment that loses the filemode (e.g. exporting ext4 via
+CIFS mount, visiting a Cygwin created repository with
+Git for Windows or Eclipse).
+In such a case it may be necessary to set this variable to 'false'.
+See linkgit:git-update-index[1].
++
+The default is true (when core.filemode is not specified in the config file).
+
+core.hideDotFiles::
+	(Windows-only) If true, mark newly-created directories and files whose
+	name starts with a dot as hidden.  If 'dotGitOnly', only the `.git/`
+	directory is hidden, but no other files starting with a dot.  The
+	default mode is 'dotGitOnly'.
+
+core.ignoreCase::
+	Internal variable which enables various workarounds to enable
+	Git to work better on filesystems that are not case sensitive,
+	like APFS, HFS+, FAT, NTFS, etc. For example, if a directory listing
+	finds "makefile" when Git expects "Makefile", Git will assume
+	it is really the same file, and continue to remember it as
+	"Makefile".
++
+The default is false, except linkgit:git-clone[1] or linkgit:git-init[1]
+will probe and set core.ignoreCase true if appropriate when the repository
+is created.
++
+Git relies on the proper configuration of this variable for your operating
+and file system. Modifying this value may result in unexpected behavior.
+
+core.precomposeUnicode::
+	This option is only used by Mac OS implementation of Git.
+	When core.precomposeUnicode=true, Git reverts the unicode decomposition
+	of filenames done by Mac OS. This is useful when sharing a repository
+	between Mac OS and Linux or Windows.
+	(Git for Windows 1.7.10 or higher is needed, or Git under cygwin 1.7).
+	When false, file names are handled fully transparent by Git,
+	which is backward compatible with older versions of Git.
+
+core.protectHFS::
+	If set to true, do not allow checkout of paths that would
+	be considered equivalent to `.git` on an HFS+ filesystem.
+	Defaults to `true` on Mac OS, and `false` elsewhere.
+
+core.protectNTFS::
+	If set to true, do not allow checkout of paths that would
+	cause problems with the NTFS filesystem, e.g. conflict with
+	8.3 "short" names.
+	Defaults to `true` on Windows, and `false` elsewhere.
+
+core.fsmonitor::
+	If set, the value of this variable is used as a command which
+	will identify all files that may have changed since the
+	requested date/time. This information is used to speed up git by
+	avoiding unnecessary processing of files that have not changed.
+	See the "fsmonitor-watchman" section of linkgit:githooks[5].
+
+core.trustctime::
+	If false, the ctime differences between the index and the
+	working tree are ignored; useful when the inode change time
+	is regularly modified by something outside Git (file system
+	crawlers and some backup systems).
+	See linkgit:git-update-index[1]. True by default.
+
+core.splitIndex::
+	If true, the split-index feature of the index will be used.
+	See linkgit:git-update-index[1]. False by default.
+
+core.untrackedCache::
+	Determines what to do about the untracked cache feature of the
+	index. It will be kept, if this variable is unset or set to
+	`keep`. It will automatically be added if set to `true`. And
+	it will automatically be removed, if set to `false`. Before
+	setting it to `true`, you should check that mtime is working
+	properly on your system.
+	See linkgit:git-update-index[1]. `keep` by default.
+
+core.checkStat::
+	When missing or is set to `default`, many fields in the stat
+	structure are checked to detect if a file has been modified
+	since Git looked at it.  When this configuration variable is
+	set to `minimal`, sub-second part of mtime and ctime, the
+	uid and gid of the owner of the file, the inode number (and
+	the device number, if Git was compiled to use it), are
+	excluded from the check among these fields, leaving only the
+	whole-second part of mtime (and ctime, if `core.trustCtime`
+	is set) and the filesize to be checked.
++
+There are implementations of Git that do not leave usable values in
+some fields (e.g. JGit); by excluding these fields from the
+comparison, the `minimal` mode may help interoperability when the
+same repository is used by these other systems at the same time.
+
+core.quotePath::
+	Commands that output paths (e.g. 'ls-files', 'diff'), will
+	quote "unusual" characters in the pathname by enclosing the
+	pathname in double-quotes and escaping those characters with
+	backslashes in the same way C escapes control characters (e.g.
+	`\t` for TAB, `\n` for LF, `\\` for backslash) or bytes with
+	values larger than 0x80 (e.g. octal `\302\265` for "micro" in
+	UTF-8).  If this variable is set to false, bytes higher than
+	0x80 are not considered "unusual" any more. Double-quotes,
+	backslash and control characters are always escaped regardless
+	of the setting of this variable.  A simple space character is
+	not considered "unusual".  Many commands can output pathnames
+	completely verbatim using the `-z` option. The default value
+	is true.
+
+core.eol::
+	Sets the line ending type to use in the working directory for
+	files that have the `text` property set when core.autocrlf is false.
+	Alternatives are 'lf', 'crlf' and 'native', which uses the platform's
+	native line ending.  The default value is `native`.  See
+	linkgit:gitattributes[5] for more information on end-of-line
+	conversion.
+
+core.safecrlf::
+	If true, makes Git check if converting `CRLF` is reversible when
+	end-of-line conversion is active.  Git will verify if a command
+	modifies a file in the work tree either directly or indirectly.
+	For example, committing a file followed by checking out the
+	same file should yield the original file in the work tree.  If
+	this is not the case for the current setting of
+	`core.autocrlf`, Git will reject the file.  The variable can
+	be set to "warn", in which case Git will only warn about an
+	irreversible conversion but continue the operation.
++
+CRLF conversion bears a slight chance of corrupting data.
+When it is enabled, Git will convert CRLF to LF during commit and LF to
+CRLF during checkout.  A file that contains a mixture of LF and
+CRLF before the commit cannot be recreated by Git.  For text
+files this is the right thing to do: it corrects line endings
+such that we have only LF line endings in the repository.
+But for binary files that are accidentally classified as text the
+conversion can corrupt data.
++
+If you recognize such corruption early you can easily fix it by
+setting the conversion type explicitly in .gitattributes.  Right
+after committing you still have the original file in your work
+tree and this file is not yet corrupted.  You can explicitly tell
+Git that this file is binary and Git will handle the file
+appropriately.
++
+Unfortunately, the desired effect of cleaning up text files with
+mixed line endings and the undesired effect of corrupting binary
+files cannot be distinguished.  In both cases CRLFs are removed
+in an irreversible way.  For text files this is the right thing
+to do because CRLFs are line endings, while for binary files
+converting CRLFs corrupts data.
++
+Note, this safety check does not mean that a checkout will generate a
+file identical to the original file for a different setting of
+`core.eol` and `core.autocrlf`, but only for the current one.  For
+example, a text file with `LF` would be accepted with `core.eol=lf`
+and could later be checked out with `core.eol=crlf`, in which case the
+resulting file would contain `CRLF`, although the original file
+contained `LF`.  However, in both work trees the line endings would be
+consistent, that is either all `LF` or all `CRLF`, but never mixed.  A
+file with mixed line endings would be reported by the `core.safecrlf`
+mechanism.
+
+core.autocrlf::
+	Setting this variable to "true" is the same as setting
+	the `text` attribute to "auto" on all files and core.eol to "crlf".
+	Set to true if you want to have `CRLF` line endings in your
+	working directory and the repository has LF line endings.
+	This variable can be set to 'input',
+	in which case no output conversion is performed.
+
+core.checkRoundtripEncoding::
+	A comma and/or whitespace separated list of encodings that Git
+	performs UTF-8 round trip checks on if they are used in an
+	`working-tree-encoding` attribute (see linkgit:gitattributes[5]).
+	The default value is `SHIFT-JIS`.
+
+core.symlinks::
+	If false, symbolic links are checked out as small plain files that
+	contain the link text. linkgit:git-update-index[1] and
+	linkgit:git-add[1] will not change the recorded type to regular
+	file. Useful on filesystems like FAT that do not support
+	symbolic links.
++
+The default is true, except linkgit:git-clone[1] or linkgit:git-init[1]
+will probe and set core.symlinks false if appropriate when the repository
+is created.
+
+core.gitProxy::
+	A "proxy command" to execute (as 'command host port') instead
+	of establishing direct connection to the remote server when
+	using the Git protocol for fetching. If the variable value is
+	in the "COMMAND for DOMAIN" format, the command is applied only
+	on hostnames ending with the specified domain string. This variable
+	may be set multiple times and is matched in the given order;
+	the first match wins.
++
+Can be overridden by the `GIT_PROXY_COMMAND` environment variable
+(which always applies universally, without the special "for"
+handling).
++
+The special string `none` can be used as the proxy command to
+specify that no proxy be used for a given domain pattern.
+This is useful for excluding servers inside a firewall from
+proxy use, while defaulting to a common proxy for external domains.
+
+core.sshCommand::
+	If this variable is set, `git fetch` and `git push` will
+	use the specified command instead of `ssh` when they need to
+	connect to a remote system. The command is in the same form as
+	the `GIT_SSH_COMMAND` environment variable and is overridden
+	when the environment variable is set.
+
+core.ignoreStat::
+	If true, Git will avoid using lstat() calls to detect if files have
+	changed by setting the "assume-unchanged" bit for those tracked files
+	which it has updated identically in both the index and working tree.
++
+When files are modified outside of Git, the user will need to stage
+the modified files explicitly (e.g. see 'Examples' section in
+linkgit:git-update-index[1]).
+Git will not normally detect changes to those files.
++
+This is useful on systems where lstat() calls are very slow, such as
+CIFS/Microsoft Windows.
++
+False by default.
+
+core.preferSymlinkRefs::
+	Instead of the default "symref" format for HEAD
+	and other symbolic reference files, use symbolic links.
+	This is sometimes needed to work with old scripts that
+	expect HEAD to be a symbolic link.
+
+core.alternateRefsCommand::
+	When advertising tips of available history from an alternate, use the shell to
+	execute the specified command instead of linkgit:git-for-each-ref[1]. The
+	first argument is the absolute path of the alternate. Output must contain one
+	hex object id per line (i.e., the same as produce by `git for-each-ref
+	--format='%(objectname)'`).
++
+Note that you cannot generally put `git for-each-ref` directly into the config
+value, as it does not take a repository path as an argument (but you can wrap
+the command above in a shell script).
+
+core.alternateRefsPrefixes::
+	When listing references from an alternate, list only references that begin
+	with the given prefix. Prefixes match as if they were given as arguments to
+	linkgit:git-for-each-ref[1]. To list multiple prefixes, separate them with
+	whitespace. If `core.alternateRefsCommand` is set, setting
+	`core.alternateRefsPrefixes` has no effect.
+
+core.bare::
+	If true this repository is assumed to be 'bare' and has no
+	working directory associated with it.  If this is the case a
+	number of commands that require a working directory will be
+	disabled, such as linkgit:git-add[1] or linkgit:git-merge[1].
++
+This setting is automatically guessed by linkgit:git-clone[1] or
+linkgit:git-init[1] when the repository was created.  By default a
+repository that ends in "/.git" is assumed to be not bare (bare =
+false), while all other repositories are assumed to be bare (bare
+= true).
+
+core.worktree::
+	Set the path to the root of the working tree.
+	If `GIT_COMMON_DIR` environment variable is set, core.worktree
+	is ignored and not used for determining the root of working tree.
+	This can be overridden by the `GIT_WORK_TREE` environment
+	variable and the `--work-tree` command-line option.
+	The value can be an absolute path or relative to the path to
+	the .git directory, which is either specified by --git-dir
+	or GIT_DIR, or automatically discovered.
+	If --git-dir or GIT_DIR is specified but none of
+	--work-tree, GIT_WORK_TREE and core.worktree is specified,
+	the current working directory is regarded as the top level
+	of your working tree.
++
+Note that this variable is honored even when set in a configuration
+file in a ".git" subdirectory of a directory and its value differs
+from the latter directory (e.g. "/path/to/.git/config" has
+core.worktree set to "/different/path"), which is most likely a
+misconfiguration.  Running Git commands in the "/path/to" directory will
+still use "/different/path" as the root of the work tree and can cause
+confusion unless you know what you are doing (e.g. you are creating a
+read-only snapshot of the same index to a location different from the
+repository's usual working tree).
+
+core.logAllRefUpdates::
+	Enable the reflog. Updates to a ref <ref> is logged to the file
+	"`$GIT_DIR/logs/<ref>`", by appending the new and old
+	SHA-1, the date/time and the reason of the update, but
+	only when the file exists.  If this configuration
+	variable is set to `true`, missing "`$GIT_DIR/logs/<ref>`"
+	file is automatically created for branch heads (i.e. under
+	`refs/heads/`), remote refs (i.e. under `refs/remotes/`),
+	note refs (i.e. under `refs/notes/`), and the symbolic ref `HEAD`.
+	If it is set to `always`, then a missing reflog is automatically
+	created for any ref under `refs/`.
++
+This information can be used to determine what commit
+was the tip of a branch "2 days ago".
++
+This value is true by default in a repository that has
+a working directory associated with it, and false by
+default in a bare repository.
+
+core.repositoryFormatVersion::
+	Internal variable identifying the repository format and layout
+	version.
+
+core.sharedRepository::
+	When 'group' (or 'true'), the repository is made shareable between
+	several users in a group (making sure all the files and objects are
+	group-writable). When 'all' (or 'world' or 'everybody'), the
+	repository will be readable by all users, additionally to being
+	group-shareable. When 'umask' (or 'false'), Git will use permissions
+	reported by umask(2). When '0xxx', where '0xxx' is an octal number,
+	files in the repository will have this mode value. '0xxx' will override
+	user's umask value (whereas the other options will only override
+	requested parts of the user's umask value). Examples: '0660' will make
+	the repo read/write-able for the owner and group, but inaccessible to
+	others (equivalent to 'group' unless umask is e.g. '0022'). '0640' is a
+	repository that is group-readable but not group-writable.
+	See linkgit:git-init[1]. False by default.
+
+core.warnAmbiguousRefs::
+	If true, Git will warn you if the ref name you passed it is ambiguous
+	and might match multiple refs in the repository. True by default.
+
+core.compression::
+	An integer -1..9, indicating a default compression level.
+	-1 is the zlib default. 0 means no compression,
+	and 1..9 are various speed/size tradeoffs, 9 being slowest.
+	If set, this provides a default to other compression variables,
+	such as `core.looseCompression` and `pack.compression`.
+
+core.looseCompression::
+	An integer -1..9, indicating the compression level for objects that
+	are not in a pack file. -1 is the zlib default. 0 means no
+	compression, and 1..9 are various speed/size tradeoffs, 9 being
+	slowest.  If not set,  defaults to core.compression.  If that is
+	not set,  defaults to 1 (best speed).
+
+core.packedGitWindowSize::
+	Number of bytes of a pack file to map into memory in a
+	single mapping operation.  Larger window sizes may allow
+	your system to process a smaller number of large pack files
+	more quickly.  Smaller window sizes will negatively affect
+	performance due to increased calls to the operating system's
+	memory manager, but may improve performance when accessing
+	a large number of large pack files.
++
+Default is 1 MiB if NO_MMAP was set at compile time, otherwise 32
+MiB on 32 bit platforms and 1 GiB on 64 bit platforms.  This should
+be reasonable for all users/operating systems.  You probably do
+not need to adjust this value.
++
+Common unit suffixes of 'k', 'm', or 'g' are supported.
+
+core.packedGitLimit::
+	Maximum number of bytes to map simultaneously into memory
+	from pack files.  If Git needs to access more than this many
+	bytes at once to complete an operation it will unmap existing
+	regions to reclaim virtual address space within the process.
++
+Default is 256 MiB on 32 bit platforms and 32 TiB (effectively
+unlimited) on 64 bit platforms.
+This should be reasonable for all users/operating systems, except on
+the largest projects.  You probably do not need to adjust this value.
++
+Common unit suffixes of 'k', 'm', or 'g' are supported.
+
+core.deltaBaseCacheLimit::
+	Maximum number of bytes to reserve for caching base objects
+	that may be referenced by multiple deltified objects.  By storing the
+	entire decompressed base objects in a cache Git is able
+	to avoid unpacking and decompressing frequently used base
+	objects multiple times.
++
+Default is 96 MiB on all platforms.  This should be reasonable
+for all users/operating systems, except on the largest projects.
+You probably do not need to adjust this value.
++
+Common unit suffixes of 'k', 'm', or 'g' are supported.
+
+core.bigFileThreshold::
+	Files larger than this size are stored deflated, without
+	attempting delta compression.  Storing large files without
+	delta compression avoids excessive memory usage, at the
+	slight expense of increased disk usage. Additionally files
+	larger than this size are always treated as binary.
++
+Default is 512 MiB on all platforms.  This should be reasonable
+for most projects as source code and other text files can still
+be delta compressed, but larger binary media files won't be.
++
+Common unit suffixes of 'k', 'm', or 'g' are supported.
+
+core.excludesFile::
+	Specifies the pathname to the file that contains patterns to
+	describe paths that are not meant to be tracked, in addition
+	to '.gitignore' (per-directory) and '.git/info/exclude'.
+	Defaults to `$XDG_CONFIG_HOME/git/ignore`.
+	If `$XDG_CONFIG_HOME` is either not set or empty, `$HOME/.config/git/ignore`
+	is used instead. See linkgit:gitignore[5].
+
+core.askPass::
+	Some commands (e.g. svn and http interfaces) that interactively
+	ask for a password can be told to use an external program given
+	via the value of this variable. Can be overridden by the `GIT_ASKPASS`
+	environment variable. If not set, fall back to the value of the
+	`SSH_ASKPASS` environment variable or, failing that, a simple password
+	prompt. The external program shall be given a suitable prompt as
+	command-line argument and write the password on its STDOUT.
+
+core.attributesFile::
+	In addition to '.gitattributes' (per-directory) and
+	'.git/info/attributes', Git looks into this file for attributes
+	(see linkgit:gitattributes[5]). Path expansions are made the same
+	way as for `core.excludesFile`. Its default value is
+	`$XDG_CONFIG_HOME/git/attributes`. If `$XDG_CONFIG_HOME` is either not
+	set or empty, `$HOME/.config/git/attributes` is used instead.
+
+core.hooksPath::
+	By default Git will look for your hooks in the
+	'$GIT_DIR/hooks' directory. Set this to different path,
+	e.g. '/etc/git/hooks', and Git will try to find your hooks in
+	that directory, e.g. '/etc/git/hooks/pre-receive' instead of
+	in '$GIT_DIR/hooks/pre-receive'.
++
+The path can be either absolute or relative. A relative path is
+taken as relative to the directory where the hooks are run (see
+the "DESCRIPTION" section of linkgit:githooks[5]).
++
+This configuration variable is useful in cases where you'd like to
+centrally configure your Git hooks instead of configuring them on a
+per-repository basis, or as a more flexible and centralized
+alternative to having an `init.templateDir` where you've changed
+default hooks.
+
+core.editor::
+	Commands such as `commit` and `tag` that let you edit
+	messages by launching an editor use the value of this
+	variable when it is set, and the environment variable
+	`GIT_EDITOR` is not set.  See linkgit:git-var[1].
+
+core.commentChar::
+	Commands such as `commit` and `tag` that let you edit
+	messages consider a line that begins with this character
+	commented, and removes them after the editor returns
+	(default '#').
++
+If set to "auto", `git-commit` would select a character that is not
+the beginning character of any line in existing commit messages.
+
+core.filesRefLockTimeout::
+	The length of time, in milliseconds, to retry when trying to
+	lock an individual reference. Value 0 means not to retry at
+	all; -1 means to try indefinitely. Default is 100 (i.e.,
+	retry for 100ms).
+
+core.packedRefsTimeout::
+	The length of time, in milliseconds, to retry when trying to
+	lock the `packed-refs` file. Value 0 means not to retry at
+	all; -1 means to try indefinitely. Default is 1000 (i.e.,
+	retry for 1 second).
+
+core.pager::
+	Text viewer for use by Git commands (e.g., 'less').  The value
+	is meant to be interpreted by the shell.  The order of preference
+	is the `$GIT_PAGER` environment variable, then `core.pager`
+	configuration, then `$PAGER`, and then the default chosen at
+	compile time (usually 'less').
++
+When the `LESS` environment variable is unset, Git sets it to `FRX`
+(if `LESS` environment variable is set, Git does not change it at
+all).  If you want to selectively override Git's default setting
+for `LESS`, you can set `core.pager` to e.g. `less -S`.  This will
+be passed to the shell by Git, which will translate the final
+command to `LESS=FRX less -S`. The environment does not set the
+`S` option but the command line does, instructing less to truncate
+long lines. Similarly, setting `core.pager` to `less -+F` will
+deactivate the `F` option specified by the environment from the
+command-line, deactivating the "quit if one screen" behavior of
+`less`.  One can specifically activate some flags for particular
+commands: for example, setting `pager.blame` to `less -S` enables
+line truncation only for `git blame`.
++
+Likewise, when the `LV` environment variable is unset, Git sets it
+to `-c`.  You can override this setting by exporting `LV` with
+another value or setting `core.pager` to `lv +c`.
+
+core.whitespace::
+	A comma separated list of common whitespace problems to
+	notice.  'git diff' will use `color.diff.whitespace` to
+	highlight them, and 'git apply --whitespace=error' will
+	consider them as errors.  You can prefix `-` to disable
+	any of them (e.g. `-trailing-space`):
++
+* `blank-at-eol` treats trailing whitespaces at the end of the line
+  as an error (enabled by default).
+* `space-before-tab` treats a space character that appears immediately
+  before a tab character in the initial indent part of the line as an
+  error (enabled by default).
+* `indent-with-non-tab` treats a line that is indented with space
+  characters instead of the equivalent tabs as an error (not enabled by
+  default).
+* `tab-in-indent` treats a tab character in the initial indent part of
+  the line as an error (not enabled by default).
+* `blank-at-eof` treats blank lines added at the end of file as an error
+  (enabled by default).
+* `trailing-space` is a short-hand to cover both `blank-at-eol` and
+  `blank-at-eof`.
+* `cr-at-eol` treats a carriage-return at the end of line as
+  part of the line terminator, i.e. with it, `trailing-space`
+  does not trigger if the character before such a carriage-return
+  is not a whitespace (not enabled by default).
+* `tabwidth=<n>` tells how many character positions a tab occupies; this
+  is relevant for `indent-with-non-tab` and when Git fixes `tab-in-indent`
+  errors. The default tab width is 8. Allowed values are 1 to 63.
+
+core.fsyncObjectFiles::
+	This boolean will enable 'fsync()' when writing object files.
++
+This is a total waste of time and effort on a filesystem that orders
+data writes properly, but can be useful for filesystems that do not use
+journalling (traditional UNIX filesystems) or that only journal metadata
+and not file contents (OS X's HFS+, or Linux ext3 with "data=writeback").
+
+core.preloadIndex::
+	Enable parallel index preload for operations like 'git diff'
++
+This can speed up operations like 'git diff' and 'git status' especially
+on filesystems like NFS that have weak caching semantics and thus
+relatively high IO latencies.  When enabled, Git will do the
+index comparison to the filesystem data in parallel, allowing
+overlapping IO's.  Defaults to true.
+
+core.createObject::
+	You can set this to 'link', in which case a hardlink followed by
+	a delete of the source are used to make sure that object creation
+	will not overwrite existing objects.
++
+On some file system/operating system combinations, this is unreliable.
+Set this config setting to 'rename' there; However, This will remove the
+check that makes sure that existing object files will not get overwritten.
+
+core.notesRef::
+	When showing commit messages, also show notes which are stored in
+	the given ref.  The ref must be fully qualified.  If the given
+	ref does not exist, it is not an error but means that no
+	notes should be printed.
++
+This setting defaults to "refs/notes/commits", and it can be overridden by
+the `GIT_NOTES_REF` environment variable.  See linkgit:git-notes[1].
+
+core.commitGraph::
+	If true, then git will read the commit-graph file (if it exists)
+	to parse the graph structure of commits. Defaults to false. See
+	linkgit:git-commit-graph[1] for more information.
+
+core.useReplaceRefs::
+	If set to `false`, behave as if the `--no-replace-objects`
+	option was given on the command line. See linkgit:git[1] and
+	linkgit:git-replace[1] for more information.
+
+core.multiPackIndex::
+	Use the multi-pack-index file to track multiple packfiles using a
+	single index. See link:technical/multi-pack-index.html[the
+	multi-pack-index design document].
+
+core.sparseCheckout::
+	Enable "sparse checkout" feature. See section "Sparse checkout" in
+	linkgit:git-read-tree[1] for more information.
+
+core.abbrev::
+	Set the length object names are abbreviated to.  If
+	unspecified or set to "auto", an appropriate value is
+	computed based on the approximate number of packed objects
+	in your repository, which hopefully is enough for
+	abbreviated object names to stay unique for some time.
+	The minimum length is 4.
