url: add trailing slashes to URLs with hostnames that don't have one
This works around a potential issue in Python 2.4 where cloning a repo
with a URL like http://foo:8080 would cause urllib2 to query on
http://foo:8080?cmd=capabilities instead of
http://foo:8080/?cmd=capabilities.
In the past, this issue has been masked by the fact that
url.getauthinfo() added a trailing slash when it was missing.
