It may be a good idea to rearrange these by order to correctness.
Correctness may not be the best way to describe it, but which is the
strongest indicator that there is a submodule or that a repo 'has a
submodule'. That way in the future we could have a #define that is
SUBMODULE_CHECK_ANY or ALL or something....Now that I'm thinking harder
about that we may not want that, and just require explicitly stating
which check you want done.
Anyways good looking patch, and I like the idea of consolidating the
checks into a single function.
