Re: 2 minor bugs with filling and comments in mail mode

[Markus Rost]

   Indeed, if comment-start-skip cannot be easily inferred from comment-start,
   the major mode needs to set it explicitly.  I've installed changes in
   sendmail.el and message.el for that.

The change in sendmail.el needs a fix:

address@hidden:~$ emacs -batch -f compose-mail
Wrong type argument: stringp, nil

The culprit is (regexp-quote mail-yank-prefix) in case
mail-yank-prefix is nil (the default value).  I couldn't immediately
guess the right fix, so I'll leave it to you.

   Thanks.  I've fixed this as well.

That works for me.
