[leafnode-list] Killed count in log incorrect?

[Laurence]

Hi, I'm running version 1.9.43.rel.  I've set up a few entries in filters
and I'm 100% sure that articles are matching and being killed.  However
running:

grep killed fetchnews.log | grep -v " 0 killed"

never returns any matching lines.  I had a quick look through the release
notes for later versions but couldn't see any mention.

Thanks,
Laurence
