Great.  FWIW, here's what the POP3 AUTH command grammar looks like (SMTP 
AUTH is similar):

	auth_command	= "AUTH" SPACE auth_type [SPACE (base64 / "=")]
			  *(CRLF [base64]) CRLF


I can't use something similar for NNTP because the grammar for a 
"simple" command ends with EOL.  In other words, the fact that NNTP 
allows trailing junk makes it a little more difficult.  I think what we 
need is for the initial line of a multi-part command to end with EOL, 
and any subsequent lines end with CRLF.  I think this would work for 
IHAVE/POST, where we start with a simple command and then continue with 
an article type response.  Just a thought, you may have a better idea.
