  	----------------------------------
  	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.
