git-svn: fix cloning of HTTP URLs with '+' in their path

With this, git svn clone -s http://svn.gnome.org/svn/gtk+
is successful.

Also modified the funky rename test for this, which _does_
include escaped '+' signs for HTTP URLs.  SVN seems to accept
either "+" or "%2B" in filenames and directories (just not the
main URL), so I'll leave it alone for now.
