;; paragraph and we let `fill-region' fill the long line into several
;; lines with the quote prefix as `fill-prefix'.
-;; Todo: encoding
+;; Todo: encoding, implement basic `fill-region' (Emacs and XEmacs
+;; implementations differ..)
;; History:
;; 2000-02-19 use `point-at-{b,e}ol' in XEmacs
;; 2000-03-11 no compile warnings for point-at-bol stuff
;; 2000-03-26 commited to gnus cvs
+;; 2000-10-23 don't flow "-- " lines, make "quote-depth wins" rule
+;; work when first line is at level 0.
