And I imagine if a submodule has such hints we could add a command say

	git submodule resolve-dependencies

which could resolve such "I need a version newer than" hints given by a
submodule to help the user to update a submodule in the superproject.

Disclaimer: I think we need to think about all the implications such a
scheme introduces very carefully. The picture is still a bit blurry for
me.
