  * Make SpecConstr work right for nullary constructors
  
  For totally stupid reasons, SpecConstr didn't work for the (particularly
  easy) case of nullary constructors like True and False.  I just had some
  equations in the wrong order, so that a Var case came first, which 
  matches a nullary constructor, with the constructor-application case
  afterwards.
  
  The fix is easy.  I did a bit of refactoring at the same time.
