SVN commit 1062490 by otrichet:

kio_nntp could send a broken XOVER request to the server and hang on an error
answer.
This corrects the broken request.

Thanks to Arkadiusz Miskiewicz for the analysis.

Arkadiusz, I change your patch because the real integer overflow is in the
test "lastSerNum - first > max". Because lastSerNum and first are
"unsigned long", when "lastSerNum" is inferior to "first", the
computation of "lastSerNum - first" overflow and give a big long and as
a consequence the test succeeds.

CCBUG: 218253
