Subject: Ignore ICS game starts when already in game
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=3fb931964b7214f293750b842495eff5774cfa8b;p=xboard.git

Ignore ICS game starts when already in game

The advance switching of the variant on game-start messages was
disruptive for users with gin=1, which also sends such messages
for other games than your own. For now fixed by only reacting on
them when idle (detected by invalid game number).
