If a user does git checkout HEAD -- path/to/submodule they'd expect the
submodule to be checked out to the commit that submodule is at in HEAD.
This is the most brute force possible way of try to do that, and so its
probably broken in some cases. However I'm not terribly familiar with
git's internals and I'm not sure if this is even wanted so I'm starting
simple. If people want this to work I can try and do something better.
