[Stalled]

* jh/receive-count-limit (2011-05-23) 10 commits
 - receive-pack: Allow server to refuse pushes with too many objects
 - pack-objects: Estimate pack size; abort early if pack size limit is exceeded
 - send-pack/receive-pack: Allow server to refuse pushing too large packs
 - pack-objects: Allow --max-pack-size to be used together with --stdout
 - send-pack/receive-pack: Allow server to refuse pushes with too many commits
 - pack-objects: Teach new option --max-commit-count, limiting #commits in pack
 - receive-pack: Prepare for addition of the new 'limit-*' family of capabilities
 - Tighten rules for matching server capabilities in server_supports()
 - send-pack: Attempt to retrieve remote status even if pack-objects fails
 - Update technical docs to reflect side-band-64k capability in receive-pack

Would need another round to separate per-pack and per-session limits.

* sr/transport-helper-fix (2011-06-19) 20 commits
 - transport-helper: implement marks location as capability
 - transport-helper: Use capname for gitdir capability too
 - transport-helper: export is no longer always the last command
 - transport-helper: change import semantics

 - transport-helper: use the new done feature where possible

 - transport-helper: factor out push_update_refs_status
 - fast-export: support done feature
 - fast-import: introduce 'done' command
 - git-remote-testgit: fix error handling

At least Patch 10/20 (git-remote-testgit: fix error handling) and Patch
15/20 (transport-helper: use the new done feature where possible) need a
reroll.

* jm/mergetool-pathspec (2011-06-22) 2 commits
 - mergetool: Don't assume paths are unmerged
 - mergetool: Add tests for filename with whitespace

I think this is a good idea, but it probably needs a re-roll.
