2822upd <obs-FWS>

Hi, in a 2616bis discussion about the wonders of "#" cum <LWS>
(= "ASCII art with commas") I mentioned how RFC 2822 + 2822upd
solved this by putting all multiple line foldings in <obs-FWS>
and saying that this is obsolete (MUST NOT generate), compare:

<http://tools.ietf.org/html/draft-resnick-2822upd-06#section-4.2> 

| FWS             =   ([*WSP CRLF] 1*WSP) /  obs-FWS
[...]
| obs-FWS         =   1*WSP *(CRLF 1*WSP)

Unless I miss something this could be made clearer with a "2":

| obs-FWS         =   1*WSP 2*(CRLF 1*WSP)
