Subject: Make EditPosition pallette work in Asian variants
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=5f5ea25ea2421cdf6d620d05548c2efa3d81783f;p=xboard.git

Make EditPosition pallette work in Asian variants

Construction of the pallette position was not working in variants that
did not have Pawns start on 2nd rank, or that had multiple ranks of pieces.
Now the algorithm is applied to all ranks.
