Clearer. JFTR, this is still "avoid *any* folding", and not
"avoid more than one folding". And if you like...
origin = "Origin:" [ SP ] origin-list-or-null
...I wonder why you don't demote HTAB generally to "obsolete"
in OWS. Or why you don't propose *WSP instead of [SP] in the
Origin header field. It would be odd if the overall HTTPbis
rules and the specific Origin header field have different
ideas about "optional white space" (modulo <obs-fold>, i.e.,
eliminating <obs-fold> in a new header field Origin is fine).
One optional SP is not the same as zero or more ( HTAB / SP ).
