  // control revision-related operation.
  // Some also have their page callbacks altered, e.g to load the latest
  // rather than the current revision of a node.
  // Can't change node load function to, say nid_load(), as we'll run into
  // trouble elsewhere, e.g. menu_get_object(), due to the fact that the
  // prefix, e.g. '%nid', is meant to be a type name, i.e. '%node'.
  //
  // Alter the 3 primary node page tabs: View tab, Edit tab, Revisions tab ...
