Hmm, I'm afraid figuring out how to write such a test would take longer than I can really spare for this issue. There don't seem to be any svn+ssh tests currently.

How about this?
git-svn: Fix svn.pushmergeinfo handling of svn+ssh usernames.
Previously, svn dcommit of a merge with svn.pushmergeinfo set would
get error messages like "merge parent <X> for <Y> is on branch
svn+ssh://gcc.gnu.org/svn/gcc/trunk, which is not under the git-svn root
svn+ssh://jason@gcc.gnu.org/svn/gcc!" So, let's call remove_username (as we do for svn info) before comparing
rooturl to branchurl.Show 16 quoted lines
