Author: Stefan Kangas <stefan@marxist.se>
Commit: Stefan Kangas <stefan@marxist.se>
Obsolete local set difference functions in favor of seq-difference
* lisp/emacs-lisp/seq.el (seq-difference): Add autoload cookie.
* lisp/gnus/gnus-range.el (gnus-set-difference):
* lisp/gnus/spam.el (spam-set-difference): Make obsolete in favor
of seq-difference. Update callers.
