This is very nice but I think it's also nice to use the `markdown'
processor directly (as markdown-mode does).  It will handle more of the
Markdown markup and generates HTML which we can then inline.  I'm not
sure--can anyone with Markdown experience comment?  This would be
Gnus-specific because the HTML result would then be part of the article
buffer.

Also it would be very useful to detect Markdown automatically based on
some traits, like 4-space indented quotes and the other Markdown markup.
