$NetBSD: patch-ad,v 1.1 2009/05/23 15:02:42 dholland Exp $

This patch fixes at least one set of "Bogus call to CARDS_RenderCard"
problems - the problem being that if the card deck ran out, the server
would start handing out card -1.

I don't know if this is the same problem we used to see back in the
day or a different one.

upstream: AFAIK upstream is currently comatose/dead
