NNTP as presently written cannot transfer an article that does not end in
a CRLF. In practice, clients will just add a CRLF to any article that
doesn't already end in one, since otherwise they can't POST.
By the time we introduce some method of transfer that can handle arbitrary
data and therefore doesn't have this problem, I suspect the Lines header
will be completely obsolete.

RFC 3977 says that you can *call* the :lines metadata element Lines:, but
it's still the metadata element. Per RFC 3977, the Lines header is no
longer used to provide the basic overview information. I think that's
what's referred to here.
