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
