I think, as will all folding in Netnews, it is a MUST accept, but SHOULD
NOT generate.

Yes, I think I fixed that in my master copy, so it will be in the next
draft.

Yes, we know about this. I am waiting for the RFC from MESSFOR to be
published to see what it finally says, but I have little hope it will have
addressed the problem. Then I shall write the proper fix into our draft.

No! No! no-fold-literal is used in phrases (e.g. people'd Real Names in
From headers, etc). It was quite deliberate to allow all UTF-8 characters
in there.

Yes, spaces in no-fold-quote and in [...] are waiting for the final
MESSFOR, as above. I have made a note to do it.
