Look at git/t/t7400-submodule-basic.sh for example at the test starting
at line 84 on how to add a submodule without any upstream.

Git has already a disadvantage against other SCM (like mercurial)
because it's "too easy to loose data with git". Meaning that we purge
unrefered commits. (Yes this is up to debate if this is good or bad, but
here's not the place).

I think we should be very carefully with adding commands that
permanently removes data. They should be really well crafted so that
there's no way to do this by mistake.
