Hmm, maybe we would need to add a --no-ff-only?  Or they could just
do:

	git fetch origin
	git merge FETCH_HEAD

What if git automaticallly set up the origin branch to have a certain
set of mergeoptions by default?  That would probably be right for most
users, but it makes it obvious what's going on when they take a look
at the .git/config file, and doesn't make the remote that happens to
have the name "origin" as having certain magic properties.  Using a
set of mergeoptions would also be bit more general, and might have
applications in the future.
