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.
