Excessive nntp reads since today

[Tassilo Horn <tassilo@member.fsf.org>]

Hi all,

since I've updated Ma Gnus today, when I want to enter some nntp group
with, say, 3 unread articles, it'll start downloading the whole
internet.  Well, seriously, it'll frequently download twenty or more MB.

My `gnus-fetch-old-headers' is 'some, so it might want to fetch some
older messages to connect new articles in a thread, but not so many.  I
just entered the gmane xetex group which had 4 new articles.  The
summary showed those 4 articles + 2 old articles from yesterday (the 4
new were replies of the 2 old ones).  But when entering the group, the
"nntp read: <x> kb" message counted to more than 12.000.

I suspect this change is the culprit, so I added Wolfgang to the Cc.
