I have a few concerns about what this is trying to do.

First, I expect performance will be terrible in repositories with large
and/or many submodules.  I'd go so far as to say that it's pretty much a
show-stopper for our repository.

Second, there are many times where I'm working in a submodule on branch
"TopicA" but not in branch "TopicB".  If I've made submodule changes in
TopicA then try to push up TopicB, won't I have have to tell push to "-f"?
But that turns off other checks that I'd rather keep.

I'd feel a lot better about this patch if the check was *off* by default and
there was a config setting / command-line option to turn it on.

I also agree with Junio that this kind of verification makes more sense in a
hook on the server side.
