The signatures on the revision.  The hash id of a revision is based on:
  - the contents of the tree
  - the ancestry of the revision

Change the ancestry, and the revision is no longer the same one.  Have
two people make the same change to a revision, and the resulting
revisions are the same revision. This really is a feature :)
