Mail digest and MIME headers

Mail digest and MIME headers

[Per Abrahamsen]

Why does "gnus-uu-digest-mail-forward" insert 

        MIME-Version: 1.0
        Content-Type: text/plain; charset=us-ascii

in each digested message?  This is the default content type, so there
should be no reason to insert the headers.

Thanks, but does it has to add the MIME-version header?  When there is
no other MIME headers?

I also found a problem with the first "Topics" entry, there is an
empty line before the "Subject: " header which makes it part of the
body, instead of part of the header.  This patch fixes that:

It's not strictly necessary, but it does say to other MUAs that you're
guaranteeing that they can assume all of the standard defaults for the
other MIME parameters, whereas if you leave off MIME-Version you're saying
that the message may not comply with MIME and could be in an unknown
character set.

Does this reasoning apply to nested messages, such as messages within
MIME digests?  

For a top-level message, I agree it is a good tradeoff, because
unknown headers are hidden by most agents, even those that are not
MIME aware.

This patch is munged because of the mml tags.  Could you resent the
patch as an attachment?

I'm fairly sure not.  Good point.
