What if we added the ability to do something like this:

[remote "origin"]
	url = git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
	fetch = +refs/heads/master:refs/heads/master
	mergeoptions = --ff-only

This would be an analog to branch.<name>.mergeoptions, but it would
apply to the source of the pull request, instead of the destination.

That way, people who do a "git pull" from Linus's tree would get the
protection of --ff-only, while pulls from submaintainer trees would
automatically get a merge commit, which is what we want.

It doesn't handle the case of a submaintainer pulling from a
maintainer in a back-merge scenario, but that should be a pretty rare
case, so maybe that's OK.
