Which RFC are you referring to?  While it is true that 821, 822 (and other
RFC's which are concerned with email messages) define the end of line as a
CRLF, I'm not aware of an RFC which defines canonical text.  The style of
late has been to define a line "as described in rfc822" or some such.  But
I don't recall any rfc which defines canonical text spanning session-layer
(or higher) protocols.  Is there one?

Do not uselessly lament your luck that is giving way, your work that has
failed, your life's plans that have all ended in despair.  Like a man long
prepared, like a man of courage, bid her farewell, the Alexandria that
leaves you.
