  -- Note that it cannot be assumed that add/subtract tests cover paths
  -- for this operation adequately, here, because the code might be
  -- quite different (comparison cannot overflow or underflow, so
  -- actual subtractions are not necessary). Similarly, comparetotal
  -- will have some radically different paths than compare.
