Benson and I were trying to use subsetp and getting wrong results. subsetp is supposed to take two lists and check all the elements of the first list are contained in the second list. (subsetp (list ?a) (list ?a ?b ?c ?d)) returns t (subsetp (list ?a ?b) (list ?a ?b ?c ?d)) returns t (subsetp (list ?a) nil) returns (?a) But should return nil. (subsetp nil (list ?a ?b ?c ?d)) returns t (subsetp nil nil ) returns nil but should return t Attached is a patch that fixes both wrong cases. _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
