Hi,

Execution of the command gnus-uu-digest-(mail|post)-forward on a
summary line will generate the form of a message body as follows:

--8<---------------cut here---------------start------------->8---
< #multipart type=digest >
< #part type=message/rfc822 >
Subject: Topics

Topics:
   subject string of an article

< #mml type=message/rfc822 >
header of an article

body of an article
--8<---------------cut here---------------end--------------->8---

There's a problem that the first `Topics' part may contain non-
ascii subject string, and it will be sent without being encoded.
Though I requested in the past and had changed the tag into #mml
from #part, it has been returned after that.  Probably, some
another problems occurred.  Then, I make a different proposal
from last time.

Isn't it possible to change the type of the first `Topics' part
from `message/rfc822' to `text/plain'?  If it is allowed, the
code can be changed as follows and the problem will be solved.
