title: Clone a branch from subversion to mercurial with complete history (even past the branch to parents)
body: <p>Is there a way to create a mercurial repository with the complete history of a subversion branch?  All the methods I have seen effectively do a stop on copy, stopping the history when the branch was created.  Is there a way to pull the entire history, back through previous branches, and even down to the trunk?</p>
