Merge branch 'lj/refs'
* lj/refs: (63 commits) Fix show-ref usagestring t3200: git-branch testsuite update sha1_name.c: avoid compilation warnings. Make git-branch a builtin ref-log: fix D/F conflict coming from deleted refs. git-revert with conflicts to behave as git-merge with conflicts core.logallrefupdates thinko-fix git-pack-refs --all core.logallrefupdates create new log file only for branch heads. Remove bashism from t3210-pack-refs.sh ref-log: allow ref@{count} syntax. pack-refs: call fflush before fsync. pack-refs: use lockfile as everybody else does. git-fetch: do not look into $GIT_DIR/refs to see if a tag exists. lock_ref_sha1_basic does not remove empty directories on BSD Do not create tag leading directories since git update-ref does it. Check that a tag exists using show-ref instead of looking for the ref file. Use git-update-ref to delete a tag instead of rm()ing the ref file. Fix refs.c;:repack_without_ref() clean-up path Clean up "git-branch.sh" and add remove recursive dir test cases. ...
