Ew. No. Ideally, it should specify the byte count counting all CRLF
pairs as two bytes. There needs to be a warning here that the byte
count may not correspond exactly to the number of octets returned by
an ARTICLE command, because in some server designs that simply isn't
predictable in advance; but that should be the target aimed for.

(An implementation wanting to pre-allocate a buffer for an article
download might choose to use bytes + 2*lines + constant slop, with
perhaps a kbyte of slop; that should behave tolerably well with
existing implementations.)
