REVISION SUMMARY
  Without this, the rewriteutil logic thinks it's found a reference to the wdir
  pseudo-revision, and then tries to look it up and rewrite it. Stop it from
  doing that.
  
  Amusingly, I had trouble working with this changeset when I didn't
  describe the defect above using a regular expression, because it would
  trigger the bug in my installed version of hg.
