One alternative would be to make the check cheaper. Could we reliably
tell from the submodule.foo.* block in the config that path "foo" is a
submodule? I think that would work after "submodule init" but not right
after "git clone". So the index really is the source of truth there.

Well we can check if there is a .gitmodules file that has a
submodule.*.path equal to the last part of $CWD, no need to look
at the git config.

And that would also work right after git clone (in an
unpopulated/uninitialized submodule as I call it).

And in my current understanding of submodules the check in
.gitmodules ought to be enough, too.

Yeah, that probably makes sense. You can have a gitlink without a
.gitmodules file, but I don't quite know what that would mean in terms
of submodules (I guess it's not a submodule but "something else").
