* jc/autogc: git-gc --auto: run "repack -A -d -l" as necessary. git-gc --auto: restructure the way "repack" command line is built. git-gc --auto: protect ourselves from accumulated cruft git-gc --auto: add documentation. git-gc --auto: move threshold check to need_to_gc() function. repack -A -d: use --keep-unreachable when repacking pack-objects --keep-unreachable Export matches_pack_name() and fix its return value Invoke "git gc --auto" from commit, merge, am and rebase. Implement git gc --auto
