bugfixed: editing attachments breaks a non-MIME forwarded part

Hi,

Try copying this message to somewhere, and [d]deleting (or
[C-o]save&stripping, [r]replacing) an attachment.  You will see
the non-MIME forwarded part broken.  I've fixed this bug in
the Gnus trunk.

-------------------- Start of forwarded message --------------------
From: Katsumi Yamaoka <yamaoka@jpl.org>
To: ding@gnus.org

このメッセージをどこかにコピーして、添付を [d]消去 (または
[C-o]保存&削除、[r]交換) してみてください。非-MIME で転送された
パートが壊れることがわかるでしょう。私はこのバグを Gnus 幹で直し
ました。
