Subject: Beef up variant detection in New Variant dialog WB
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=1041d8a7aa236941d133d8992dbe0fb39fd57b53

Beef up variant detection in New Variant dialog WB

In WinBoard the enabling of radio buttons was still done when the
variant nameon the button was a sub-string of the variants feature,
without requiring a match of the full name (so that 'grande-acedrex'
would enable the 'grand' button of Grand Chess).
