Subject: Do not recognize non-ICS variants from PGN event tag
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=42011a3865940552276f9de4b8fe41a4e2c14946;p=xboard.git

Do not recognize non-ICS variants from PGN event tag

These variants were introduced after supporting the variant tag, so if
the variant tag is missing, their recognition from the event tag will be
a false match. (Mainly to prevent events with 'super' in the name being
recognized as Superchess.)
