;;	tower@prep.ai.mit.edu Wed Oct 29 1986
;; brought posting code almost up to the revision of RFC 850 for News 2.11
;; - couldn't see handling the special meaning of the Keyword: poster
;; - not worth the code space to support the old A news Title: (which
;;   Subject: replaced) and Article-I.D.: (which Message-ID: replaced)
;;	tower@prep Nov 86
;; changed C-c C-r key-binding due to rename of news-caesar-buffer-body
;;	tower@prep 21 Nov 86
;; added (require 'rnews)	tower@prep 22 Apr 87
;; restricted call of news-show-all-headers in news-post-news & news-reply
;;	tower@prep 28 Apr 87
;; commented out Posting-Front-End to save USENET bytes tower@prep Jul 31 87
;; commented out -n and -t args in news-inews     tower@prep 15 Oct 87
