;;; Commentary:
;; - comment-box in TeXinfo generate bogus comments @ccccc@
;; - uncomment-region with a numeric argument can render multichar
;; comment markers invalid.
+;; - comment-indent or comment-region when called inside a comment
+;; will happily break the surrounding comment.
+;; - comment-quote-nested will not (un)quote properly all nested comment
+;; markers if there are more than just comment-start and comment-end.
+;; For example, in Pascal where {...*) and (*...} are possible.
;;; Todo:
;; - support gnu-style "multi-line with space in continue"
;; - somehow allow comment-dwim to use the region even if transient-mark-mode
;; is not turned on.
-;; - (from c-comment-line-break-function): c-ignore-auto-fill so that you can
-;; auto-fill comments but not code. This should probably be moved directly
-;; inside do-auto-fill.
