Subject: Fix printing of 'x' in position diagram
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=9089c023e881715fe42fe104d24df44489cd3e35

Fix printing of 'x' in position diagram

The times where 'x' was used as PieceToChar result for an empty square
are long behind us; 'x' now is a valid piece ID.
