From: Nguyễn Thái Ngọc Duy Date: Sun, 3 Feb 2013 05:53:27 +0000 (+0700) Subject: status: show the branch name if possible in in-progress info X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=0722c805d616eb644a868a995b891470f9e5e30d;p=git.git status: show the branch name if possible in in-progress info The typical use-case is starting a rebase, do something else, come back the day after, run "git status" or make a new commit and wonder what in the world's going on. Which branch is being rebased is probably the most useful tidbit to help, but the target may help too. Ideally, I would have loved to see "rebasing master on origin/master", but the target ref name is not stored during rebase, so this patch writes "rebasing master on a78c8c98b" as a half-measure to remind future users of that potential improvement.
