ietf-nntp LISTGROUP can't return 412

[Russ Allbery]

(Sorry about the flurry of messages; I'm auditing the entire draft against
INN and sending messages as I see things.  Hopefully the individual
messages will make tracking each separate issue easier.  This one should
have been combined with the previous note, but I didn't see it before I
sent the last message.)

The LISTGROUP list of response codes in 9.5.1.1.1 includes:

    412 Not currently in newsgroup

That response seems nonsensical for LISTGROUP; LISTGROUP can be used
instead of the GROUP command, and it's therefore entirely valid to use
outside of a newsgroup.  I don't believe 412 is a valid response to a
LISTGROUP command.

Similarly, the examples section has:

    Example of an attempt to retrieve an article when the current 
    group selected is empty 
            [S] 200 NNTP Service Ready 
            [C] LISTGROUP example.empty.newsgroup 
            [S] 412 No current article selected  

This example makes no sense (particularly the description).  A copy and
paste error of some sort?  Perhaps the example was intended to be:

    Example of a successful execution with a group without any articles
            [S] 200 NNTP Service Ready
            [C] LISTGROUP example.empty.newsgroup
            [S] 211 list of article numbers follows
            [S] .
