Subject: Limit auto-extending to click on first move of PV
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=9d51fbcf5ae0885f2e4855cc8805f3684dd8e0d9;p=xboard.git

Limit auto-extending to click on first move of PV

Even when auto-exted on clicks on the tail of a PV will no longer cause
any moves to be added to the game. Only clicks on or before the first
move can do that now.
