util: fix url.__str__() for windows file URLs Before: >>> str(url('file:///c:/tmp/foo/bar')) 'file:c%3C/tmp/foo/bar' After: >>> str(url('file:///c:/tmp/foo/bar')) 'file:///c%3C/tmp/foo/bar' The previous behaviour had no effect on mercurial itself (clone command for instance) because we fortunately called .localpath() on the parsed URL. hgsubversion was not so lucky and cloning a local subversion repository on Windows no longer worked on the default branch (it works on stable because de7e2fba4326 defeats the hasdriveletter() test in url class). I do not know if the %3C is correct or not but svn accepts file:// URLs containing it. Mads fixed it in de7e2fba4326, so we can always backport should the need arise.
