Fix auto-formatting of comments in auto-fill-mode This patch makes auto-fill-mode properly format comments (when lines are automatically broken). It looks strangely similar to that of: | 1999-06-24 Bob Weiner <weiner@beopen.com> | | * simple.el (indent-new-comment-line): Locally bound | `block-comment-start' to `comstart' or else when this is called | from do-auto-fill, e.g. in Lisp mode, it will insert any non-nil | `block-comment-start' value, ignoring any existing spacing after a | comment prefix in the previous line and producing ugly comments.
