Consider the following scenario:
git checkout not-the-master
work work work
git rebase --autostash upstream master
Here 'rebase --autostash <upstream> <branch>' incorrectly moves the
active branch (not-the-master) to master (before the rebase).
The expected behavior: (58794775:/git-rebase.sh:526)
AUTOSTASH=$(git stash create autostash)
git reset --hard
git checkout master
git rebase upstream
git stash apply $AUTOSTASH
The actual behavior: (6defce2b:/builtin/rebase.c:1062)
AUTOSTASH=$(git stash create autostash)
git reset --hard master
git checkout master
git rebase upstream
git stash apply $AUTOSTASH
This commit reinstates the 'legacy script' behavior as introduced with
58794775: rebase: implement --[no-]autostash and rebase.autostash
As with this commit the reset must never change the active branch,
the 'HEAD is now at ...' message has now been removed.
