rmail-reply ignores reply-to if rmail-enable-mime

[Frederik Fouvry]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

In GNU Emacs 21.2.1 (i686-pc-linux-gnu, X toolkit)
 of 2002-09-02 on cc.at.coli.uni-sb.de
configured using `configure  --prefix=/usr'
Important settings:
  value of $LC_ALL: nil
  value of $LC_COLLATE: nil
  value of $LC_CTYPE: nil
  value of $LC_MESSAGES: nil
  value of $LC_MONETARY: nil
  value of $LC_NUMERIC: nil
  value of $LC_TIME: nil
  value of $LANG: nil
  locale-coding-system: nil
  default-enable-multibyte-characters: t

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

In RMAIL, if rmail-enable-mime is set to t and the "Reply-To:"
header is hidden, then (rmail-reply) ignores the Reply-To field,
i.e. the To: field is constructed from the "From:" field, not
from "Reply-To:".

If the headers are displayed (e.g. after pressing `t'), or if
rmail-enable-mime is nil, then the Reply-To: header is respected
and the mail buffer with the reply contains the correct
addressee.

(I tried this with emacs -q.)
