[PATCH] doc: replace "--" with {litdd} in credential-cache/fsmonitor

[PATCH] doc: replace "--" with {litdd} in credential-cache/fsmonitor

[Todd Zullinger]

Asciidoc renders `--` as em-dash.  This is not appropriate for command
names.  It also breaks linkgit links to these commands.

Fix git-credential-cache--daemon and git-fsmonitor--daemon.  The latter
was added 3248486920 (fsmonitor: document builtin fsmonitor, 2022-03-25)
and included several links.  A check for broken links in the HTML docs
turned this up.

Manually inspecting the other Documentation/git-*--*.txt files turned up
the issue in git-credential-cache--daemon.

While here, quote `git credential-cache--daemon` in the synopsis to
match the vast majority of our other documentation.

Looks very sensible.

While the credential--cache fix is technically not due to a regression in
the 2.36.0 cycle, the fsmonitor--daemon one is, and it does not make sense
to do only one during the -rc phase.

FWIW I just looked at
https://git-scm.com/docs/git-credential-cache--daemon to verify that it
indeed renders the double-dash as a long dash.

I am not quite certain that using `{litdd}` in a `linkgit` construct works
both in AsciiDoc and AsciiDoctor, but I trust that you have verified that
this works.

Thank you for doing this,
Johannes

Looks good, for the linkgit case let's check it in "make check-docs":

I did not do a build with asciidoc, but when I still built
the Fedora packages with asciidoc, we had already fixed
similar issues with `{litdd}` and I don't believe that has
changed.  If it has, then we've got other broken links:

    $ git grep 'linkgit:[^]]+\{litdd\}[^]]*\[' -- Documentation/ | wc -l
    8

    $ git grep 'linkgit:[^]]+--[^]]*\[' -- Documentation/ | wc -l
    0

And thank you for reviewing and testing.

Excellent, thanks!  I had run the lint-docs-gitlink target
to see if it reported any issue, but it hadn't.  With this,
prior to the change I made to git-update-index.txt, it
properly reports the issue:

    make -C Documentation/ lint-docs-gitlink
    ...
	LINT GITLINK git-update-index.txt
    git-update-index.txt:531: error: git-fsmonitor--daemon[1]: should link '--' as '{litdd}'), shown with 'HERE' below:
    git-update-index.txt:531:	'linkgit:git-fsmonitor--daemon[1]' <-- HERE
    make: *** [Makefile:442: .build/lint-docs/gitlink/git-update-index.ok] Error 1
    make: *** Deleting file '.build/lint-docs/gitlink/git-update-index.ok'
    make: Leaving directory '/src/git/Documentation'

Cheers,

Yup, note that it'll find the other one(s) too if you pass the "-k" flag
to make, i.e. it's erroring out and aborting on the first error (as is
make's default behavior).

It won't help with all the changes you made though, e.g. headers etc. We
could add that, but it would be bigger change. This seemed easy enough
for a proposed squash-in.

Thanks for the fix!
