I looked at this earlier, but tools.ietf.org is down for me currently. I
take it this is about obs-fold in the OWS preceding field-value? I do a-
gree there is something not right here, but I am unsure if this is about
the grammar or the "any ... that matches", the latter for instance could
mean "an abstract syntax tree generated from the formal grammar where
one of the nodes is..." versus "a whole <production> that matches ...".
