the former functions.
Document #'subsetp, #'union, #'intersection, #'set-difference,
#'set-exclusive-or and their destructive analogues in this file.
* lispref/lists.texi (Association Lists):
Document #'assoc*, #'rassoc* in this file. Document #'assq,
#'assoc, #'rassq, #'rassoc in terms of the first two functions.
* lispref/objects.texi (Equality Predicates):
