ietf-nntp Editing error in section 4.1

[Russ Allbery]

(Apologies if this was already reported.  I didn't see it in a quick scan
of the archives.)

There appears to be an editing error in section 4.1 of draft 13; there are
two versions of what appears to be the same paragraph, one after another,
like new wording was added and the old wording wasn't removed:

            The server MUST respond to any command with the appropriate 
            generic response (given in section 4.1.1) if it represents the 
            situation. Otherwise, each recognized command MUST return one 
            of the response codes specifically listed in its description 
            or in an extension. A server MAY provide extensions to this 
            specification, including new commands, new features of 
            existing commands, and other ways of changing the internal 
            state of the server. However, the server MUST NOT produce any 
            other responses to a client that does not invoke any of the 
            additional features. (Therefore a client that restricts itself 
            to this specification will only receive the responses that are 
            listed). 

followed by

            Each recognized command MUST return 501 (as above) or one of 
            the response codes specifically listed in its description or 
            in an extension. A server MAY provide extensions to this 
            specification, including new commands, new features of 
            existing commands, and other ways of changing the internal 
            state of the server. However, the server MUST NOT produce any 
            other responses to a client that does not invoke any of the 
            additional features. (Therefore a client that restricts itself 
            to this specification will only receive the responses that are 
            listed). 

I believe the second paragraph is obsolete and should be removed.
