This literally does a "checkout" behind the scenes, so it is still
manipulating your working tree. It is basically the equivalent of:

  git checkout topic && git rebase upstream

The actual rebasing happens on a detached HEAD, but you will find at the
end of such a rebase that you are now on the branch "topic".
