git-svn: Finding the svn-URL of the current branch in git

Hi there,

when running "git-svn dcommit" git-svn tries to find the svn-URL of the current branch int git by looking for the most recent git log-entry corresponding to a commit in svn (see working_head_info in git-svn). In case a merge just happended this might be the URL of another branch. Would using "log --first-parent" instead of a plain "log" take care of this problem or would it have other undesirable consequences?
