Subject: Fix 50-move counter in ICS mode
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=76eeac799f3f52daca65d22d124cba0a0f9ee691;p=xboard.git

Fix 50-move counter in ICS mode

Marking irreversible moves in the EP_STATUS did not work in ICS mode,
as ApplyMove,which did that is never executed there. Only the boards
sent by ICS are displayed,especially in observing mode. Now the status is
derived from the ICS mov strings (x in the SAN move, or P in the long move.
