Yeah, I actually wrestled with finding the shortest recipe to convince
git-submodule to actually call git-fetch. Suggestions welcome if there's
something more canonical.

But I think we have to advance the submodule pointer in some way to
convince it to want to fetch (I also tried deleting the refs in the
cloned module, but that seemed hacky).

I guess the way it would happen in real life is that the "origin" remote
("super" here, not "super-clone") would make the change and commit the
submodule, and then "super-clone" would pull it.

That seemed even more convoluted to me.
