Subject: Pass command to DoCommand through global command queue
X-Git-Tag: v4.0~22
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=0bcc18ddfe1e849b345a565850e2a14cdab30d1a;p=uci2wb.git

Pass command to DoCommand through global command queue

Rather than passing the command to process as a parameter to DoCommand,
we now append it to a global 'command queue', from which DoCommand() then
reads the first line. This in preparation for letting the engine thread
handle the difficult commands.
