Subject: Fix engine-defined variant as startup
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=c1115828b95f029c8623c0af540a6c4fcdc34f39;p=xboard.git

Fix engine-defined variant as startup

Non-standard names were all recognized as 'normal' in InitBackend1().
Now if the -variant argument was not "normal", it is assumed to be an
engine-defined variant if we run with engine.
