There is some information in emacs-mime.texi:

,----[ (info "(emacs-mime)Flowed text") ]
| The Emacs MIME library will respect the `use-hard-newlines' variable
| (*note Hard and Soft Newlines: (emacs)Hard and Soft Newlines.) when
| encoding a message, and the "format=flowed" Content-Type parameter when
| decoding a message.
| 
|    On encoding text, regardless of `use-hard-newlines', lines
| terminated by soft newline characters are filled together and wrapped
| after the column decided by `fill-flowed-encode-column'.  Quotation
| marks (matching `^>* ?') are respected.  The variable controls how the
| text will look in a client that does not support flowed text, the
| default is to wrap after 66 characters.  If hard newline characters are
| not present in the buffer, no flow encoding occurs.
| [...]
`----

IMHO, it won't hurt to add a short note and reference to this
explanation in gnus.texi and message.texi.  The only occurrence is in
the "New Features" section (info "(gnus)Oort Gnus").  Suggestions?

Thanks.  AFAICS this fixed the problem.

Bye, Reiner.
