bug#36821: 27.0.50; Gnus/message.el does not support format=flowed out-of-the-box

[Toon Claes]

This is a report following a discussion on reddit:
https://www.reddit.com/r/emacs/comments/chkxeo/gnus_and_formatflowed/

I'd like to have Gnus and message.el to properly support format=flowed.

There are some instructions on doing this on
https://www.emacswiki.org/emacs/GnusFormatFlowed but this are cumbersome
and don't seem to go without any downside. Although I'm not sure
everything there is still accurate.
