ietf-nntp New wording on article numbers

[Clive D.W. Feather]

John Line (hi, John) said:
> The server should never reuse an article number. The GROUP command, however,
> is providing an indication of the range of articles which is currently 
> available, and that may quite legitimately be smaller due to cancellation.
[...]
> I've just confirmed that the INN 1.4unoff4 and 1.5 GROUP command shows the
> highest available article number, not the highest that has existed prior to
> cancellation. It is therefore the way (some widely used) current server
> software behaves, and readers don't seem to have any problems with it, and the
> wording should therefore not exclude that implementation.

I've changed the wording accordingly.
