-x [number] forces fetchnews to reconsider the last "number" articles
for fetching. That is, if the last article fetched in a particular
newsgroup was 12547 and you run fetchnews with "-x 1000", it would
retrieve message ids from all articles since 11547 and look whether
they are already available.
Unfortunately, you cannot set the value differently for each group.
This means that in a high-traffic group with 200 articles a day, you
will reconsider the last five days on average, whereas in a low-traffic
group with 5 articles a day, you will reconsider the last 200 days.
Therefore you should use this feature only together with "maxage".

NEWNEWS is only supported by a minority of servers. Of course, it
might be sensible to either give fetchnews an option "have_newnews"
or check every server with NEWNEWS and only use the traditional
method of fetching when this fails.
No code exists which implements either of these features.
