Thanks for digging.  I wouldn't be surprised if this were a fallback
to help a broken entry in .gitmodules that lack .path variable, but
we shouldn't be sweeping the problem under the rug like that.  

I wonder if we should barf loudly if there shouldn't be a submodule
at that path, i.e.

	if (!submodule)
		die("there is no submodule defined for path '%s'"...);

though.

Good thinking.  As this is "cleanup" series, I think it is within
its scope to remove an API function that becomes unused.
