Subject: Fix FEN castling rank for Knightmate
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=f2bdbde59c9d7595411bac5bc3a247b5336a3534

Fix FEN castling rank for Knightmate

The newly introduced castlingRank array was not correctly set on reading
a FEN for Knightmate, because it was looking for Kings rather than
Unicorns.
