What I meant here with 'proper' was, I guess something incorporating
both the idea that you had taken care with the formatting, and that
it was in a form that could be used both for email and on web pages
without touching it.

Understood.  I'm trying to find out which paths are possible and workable
to achieve that.

Mmm.  Ok.  I see the problem.

To handle this, it seems like we then need either an in-channel or
out-of-channel indication of formatting type, because the two options
really can't be handled cleanly by guessing (which is what we have to
do currently).  That of course would let us support anybody's choice
of formatted plaintext, flowed plaintext, html, various wiki markups,
markdown, restructured-text, and whatnot.

That should be quite easy to accomplish.

Right.  Here you actually would have been best off with the ability to
have paragraphs handled as flowed, but the ascii-art handled as pre-
formatted text.

Ok, this increased my understanding of the problem.  I think for the
future, in order to be able to support mixed flowed/formatted text,
we need to support some kind of markup language.

Best regards,
