Merge branch 'bw/rebase-autostash-keep-current-branch'

"git rebase --autostash <upstream> <branch>", when <branch> is
different from the current branch, incorrectly moved the tip of the
current branch, which has been corrected.

* bw/rebase-autostash-keep-current-branch:
builtin/rebase.c: Remove pointless message
builtin/rebase.c: make sure the active branch isn't moved when autostashing
