Now I am even more confused.

The approach I suggested in a few paragraphs above, to which you
just said "I like this change", is about making "git submodule
update" to use the url configured in the upper level repository
when it runs "git fetch".  I am looking at around l.238 of
git-submodule.sh.  In the current code, it runs "git-fetch"
without any parameter, which would allow it default to origin or
whatever, which may or may not be desirable depending on where
the 'origin' points at.  If you make that particular git-fetch
explicitly say where the fetch should be done from, wouldn't it
fix the issue for that codepath?  Why does it still require
origin?
