title: Can an SVN repository be cloned when there are branches in the history with invalid names?
body: <p>I have an SVN repository that I would like to clone using git-svn, but in the murky past of this SVN repo there were some branches made with spaces in the name...</p>
  
  <p>When I try to clone, git-svn fails with invalid object name on the revision with said branches.</p>
  
  <p>Is there a way to get around this problem, that doesn't involve starting the clone after the failing revision?</p>
