Thanks.  Cc-ing Jens, who wrote that test and knows this code much
better than I do. :)

I'm not sure what the exact semantics should be here, though that's
mostly because of my unfamiliarity with submodules in general.

If I have '[submodule "favorite"] ignore = all' and I then replace
that submodule with a blob, should "git submodule status" not mention
that path?

If I just renamed a submodule, will 'module_name "$path"' do the right
thing with the old path?
