* 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.
