Yes, RFC 2822 covers a lot of ground; I selected the appropriate

because it _does_ give some sort of approval to the "Re: " hack.
No, (as is sometimes the case where "MAY" is used) it states
an obvious fact; true the Subject field body may start with
"Re: " -- it may also start with "Blurfl" or any other content
consistent with the defined (viz. unstructured) syntax. Once
a message has been sent, there is no defined meaning (in a
protocol sense) to any part of a Subject field; users (or UA
authors) can make guesses, but guesses are sometimes wrong
and play no role in a well-designed protocol.
