git svn: branch/tag commands detect username in URLs

svn+ssh:// repositories often have userinfo embedded in the URL
which were stripped out of the "git-svn-id:" trailers.  Since
the SVN::Client::copy function takes userinfo into account when
matching URLs for SVN repositories, we need to retrieve the full
URL with embedded userinfo in it to avoid mismatched URLs.
