  * Some refactoring of SpecConstr
  
  This was originally to improve the case when SpecConstr generated a
  function with an unused argument (see Trac #4941), but I ended up
  giving up on that.  But the refactoring is still an improvement.
  
  In particular I got rid of BothOcc, which was unused.
