Subject: Fix GUI book after setup position
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=913d225a639d57b15e06f980d678871bd5556867;p=xboard.git

Fix GUI book after setup position

The routine to send move to the engine would automatically append a 'go'
is a preious setboard had put the engine in force mode, but this should
not happen on a book hit, where the engine should even be put in force mode
if it was not yet there.
