Thanks, after I sent it I realized that --quit should probably clear 
refs/rewritten as well, so I'll re-roll with that added. (One could 
argue that a user might want them after quitting the rebase but there is 
no way to clean them up safely once we've deleted the state files and I 
suspect most users would be suprised if they were left laying around)
