Subject: Fix crash at match end
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=a6cb149215f419331165e3f8e484bcc492e7b9b1;p=xboard.git

Fix crash at match end

The -afterTourney option had broken old-style matches, because the ranking
string that was tested for "busy" is not set there at all, and remains a
NULL pointer, which strcmp doesn't like.
