I have added for now:

     The ABNF for the Expect header field has been both fixed (allowing
     parameters for value-less expectations as well) and simplified
     (allowing trailing semicolons after "100-continue" when they were
     invalid before).  (Section 9.3)

(<http://trac.tools.ietf.org/wg/httpbis/trac/changeset/1495>)

...just so the text as checked-in is complete.

Now with respect whether we should make this change (allowing trailing 
semicolons): I'm open to reversing that, but in that case Prefer should 
match that. That being said, I think the harm done by not allowing them 
in both is bigger than the new edge case we introduce for 100-continue 
matching.

Best regards, Julian
