Johannes Schindelin c9e6589288 rebase -i: fix for optional [branch] parameter
When calling "git rebase -i <upstream> <branch>", git should switch
to <branch> first.  This worked before, but I broke it by my
"Shut git rebase -i up" patch.

Fix that, and add a test to make sure that it does not break again.

This test runs git rebase "interactively", by faking an edit, and verifies
that the result still makes sense.
