Subject: Fix ICS castling rights
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=0300f988935df94f3faeac3e3dbddbd6e8122fe3;p=xboard.git

Fix ICS castling rights

Copying the castling rights together with CopyBoard seems to have
broken handling of ICS rights, where ParseBoard12 prepares a board
in a local variable, an copies it before parsing the rights.
