Subject: Parse 'difficult' commands in separate routine
X-Git-Tag: v4.0~23
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=f9b3d49480bbbf3200dde21ca58dcd5ae41bcfa1;p=uci2wb.git

Parse 'difficult' commands in separate routine

The parsing of (most) commands that can only be executed when not searching
is now put in a separate routine DoCommand(). This in preparation for
having the engine thread do this.
