Subject: Don't forget to NULL out the new game id notification callback, or
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=be6bb379bb9ead46794a289ff8a68c7f5a2ede89;p=sgt-puzzles.git

Don't forget to NULL out the new game id notification callback, or
else it might start off accidentally initialised to nonsense in front
ends which don't use it.
