Good point. Originally, we did the rebase directly on the branch, though
I'm not sure if we did "checkout $branch && reset $onto" or "branch -f
$branch $onto && checkout $branch". These days we operate on a detached
HEAD, and we seem to "checkout $onto^0", which should do the
optimization you mention.
