And there's no way to tell the difference either.  I just spent a
few minutes digging around git-am and git-rebase and realized there
really isn't a way to tell these two user level commands apart as
git-rebase (by default) calls git-am and there's no marker to say
it was started by rebase.

But more than that I have to wonder why git-am still uses .dotest
in the working directory for its state management.  Why don't we
move it into $GIT_DIR like we do for `rebase -m`?

I love the idea too.  I've actually walked away from a rebase -i and
come back the following day and forgotten that I was in the middle
of a rebase and just thought I was sitting on a detached checkout.
Really confused me for a few minutes when code I was looking for
wasn't found (it was still pending to be applied by rebase -i).
