Okay, I just checked that xen doesn't use submodules but uses simple
embedded repos ignored by the .gitignore file. From a quick glance
it looks like handling the sub projects is scripted in the Makefiles.
This is perfectly fine, but then you can't really expect git commands
to know about these sub projects. Or am I missing something?
