Subject: Also treat 'result' command immediately
X-Git-Tag: v4.0~48
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=e4503efed01f5923d70288d6a7f50de29c27f0b7;p=uci2wb.git

Also treat 'result' command immediately

WinBoard has the nasty habit of sending a 'result' command just before
'quit' when it is closed while the engine is thinking, without putting
the engine in force mode first. So this command has to abort thinking too.
To prevent this will start a ponder search, 'result' now puts us in
force mode.
