Subject: git-branch -v: show the remote tracking statistics
X-Git-Tag: v1.6.0-rc0~88^2~2
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=94fcb730ff665d356689f3d30e20e0fd75c6f62f;p=git.git

git-branch -v: show the remote tracking statistics

This teaches "git branch -v" to insert the remote tracking statistics in
brackets, just before the one-liner commit log message for the branch.
