From 0722c805d616eb644a868a995b891470f9e5e30d Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Nguy=E1=BB=85n=20Th=C3=A1i=20Ng=E1=BB=8Dc=20Duy?= Date: Sun, 3 Feb 2013 12:53:27 +0700 Subject: status: show the branch name if possible in in-progress info MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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.
