Hi Lars,

I just had an interchange of smime encrypted and signed messages with
Jens Lechtenboerger.

He confirms that a message with latin-1 chars, which is encrypted and
signed, is not correctly decrypted in the sense that the latin-1 chars
are not correctly displayed and superflusios text is added.

The culprits are 
(defun mm-possibly-verify-or-decrypt (parts ctl &optional from)

And the following commits

 commit 4ce81556b7ad7f7f8c8bb07a7a935114bbe850d0
 Author: Lars Ingebrigtsen <larsi@gnus.org>
 Date:   Mon Sep 23 18:23:22 2019 +0200

     Make mm-possibly-verify-or-decrypt pass decryption error

     * lisp/gnus/mm-decode.el (mm-possibly-verify-or-decrypt): If
     there's an error, report the error back in a new part (bug#25649).

Now message cannot be decrypted anymore

** Git repaired
 commit 84ef1ea8b524f8998fc8674b99cf8069e38dce4f (HEAD)
 Author: Lars Ingebrigtsen <larsi@gnus.org>

      Make it possible to view S/MIME verified emails

      * lisp/gnus/mm-decode.el (mm-possibly-verify-or-decrypt): When
      dissecting the result, we need a header (bug#18393).

      * lisp/gnus/mm-view.el (mm-view-pkcs7-verify): Insert the verified
      string.

      * lisp/gnus/smime.el (smime-verify-region): Return the verified
      string.

Message can be decrypted, but latin-1 chars are not decoded.

If you want we can run some experiements, but you need to have a smime
certificate installed.


For me it is so annoying that I partially reverted these commits in the
latest emacs master. Here is the diff (I would not call it a patch).
