You know, you can just say you don't like it. ;)

No, that would defeat the purpose. The problem is that we have no idea
what has happened since the initial "git am". The user may have made
commits they want to keep, and we don't want to reset those away. They
may even have pulled, which means ORIG_HEAD can no longer be trusted for
a reset.

I think you raise a good point here. If we do decide to stop doing the
reset automatically, it is probably better not to simply stop doing it
(as my patch does), but to downgrade it to a warning ("You probably want
to reset, etc...").
