Subject: Allow a list of best moves in EPD
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=36d1207becf35a3918d561fb3b4d8b8b0b2d28ea

Allow a list of best moves in EPD

All characters upto a semicolon (rather than space) are now read as bestMove
string. For checking the correctness of a solution all moves in this string
are parsed and compared.
