git-svn fetch doesn't like spaces in branch names

mini:TextMateBundles mjc$ git-svn fetch
Found possible branch point: http://macromates.com/svn/Bundles/trunk/Tools/Dialog 
  PlugIn => http://macromates.com/svn/Bundles/branches/Dialog PlugIn  
Completion Menu, 8089
Initializing parent: Dialog PlugIn Completion Menu@8089
Bad URL passed to RA layer: Malformed URL for repository at /opt/local/ 
bin/git-svn line 1607

looks like that might need to be %20 ?
