[PATCH] Add test for git rebase --abort

[Mike Hommey <mh@glandium.org>]

We expect git rebase --abort to come back to the original (pre-rebase)
head, independently from when it's run during a rebase.

 I wrote this test because I spotted a problem with git rebase --abort, and
 expanded the test to other cases that work, but that it is still better to
 have a test for.

 The failing test is the third. I don't have enough knowledge in git-rebase
 to write an appropriate fix, but the problem seems to be in
 move_to_original_branch, where testing head_name doesn't seem appropriate.
