Subject: wwwstream: show relative coderepo URLs correctly

wwwstream: show relative coderepo URLs correctly

Trying to link "foo.git" relative to the current URL usually
does not provide correct results, so prefix it by going
into the parent directory if an absolute (or protocol-relative)
URL is not supplied.
