Hi Mark,

I have a use case where this would be very handy -- two teams geographically
separated. But in the end I think I disagree with it: it's not up to me, as the
person creating a superproject, to decide that anyone who forks or clones it
also has to clone all the submodules.

Instead they can decide themselves by editing .git/config between "git submodule
init" and "git submodule update", or by branching .gitmodules.

By the way:

If you source git-parse-remote, you can use

                realrepo="$(get_remote_url "$(get_default_remote)")$repo"
