Subject: Fix piece command after ID-suffix patch
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=1c76e2f7041aae8763d5ef06578e1d93e9bc900d

Fix piece command after ID-suffix patch

Piece IDs without suffix or & behind them to make them count for both
colors were no longer recognized in 'piece' commands, because there
was a null character behind the extracted piece-name field. And this
null character was seen as occurring in the suffix string.
