subrepo: fix cloning of repos from urls without slash after host (issue2970) This fixes a regression introduced with the new url handling in 1.9. This should perhaps be fixed in the url class instead, but that might be too invasive for a stable bugfix.

To run the tests, do:

cd tests/
python run-tests.py
