1. Bruce elimites obs-qp, even though it can match a few pairs
quoted-pair cannot, such as "\" DEL.
No, "\" DEL is in fact permitted by the regular syntax. The missed ones
are "\" (NUL / LF / CR)
2. I think I found a case in which Bruce permits CFWS where it wasn't
before, although I cannot decipher my very cramped margin notes. It
was something like "To: blah: (cfws) a(_at_)b(_dot_)org;".
No, that was always allowed, because a dot-atom can always be preceded by
CFWS. But it is a good example of how hard it can be to check some of
these cases in the present syntax.
3. The date syntax is reordered, and four-digit years seem to have
disappeared from the obsolete syntax. This looks like a good idea:
I don't think 4DIGIT was ever in obs-year. Nor even in RFC 822?
7. There may be a few cases where FWS in 2822 is replced by CWFS in
Bruce's grammar. It's a little hard to tell. For example, in Bruce's
grammar there always is CFWS following field-name ":", I'm not sure
the same holds for 2822. It may.
Not so. Look at orig-date, for example, where it is explicitly [FWS] that
follows the ":".
