----------------------------------
Make exprArity give the right answer
----------------------------------

MERGE INTO 5.00.2

This fixes a fairly long-standing bug in exprArity, dating from
the time we allowed arguments to be non-atoms. If f had arity
2, it was saying that

f (factorial x)

had arity 2, as well, which is plain wrong.
