Hi,

I like where this is going.

I am not sure whether we should die here. What about submodules that
have not been initialized and or cloned? I think that is a quite regular
use case for example for libraries that not everyone needs or big media
submodules which only the design team uses. How about skipping them (maybe
issuing a warning) by returning 0 here and proceeding?
