Subject: Fix erasing and exposing of arrow on secondary board
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=5fc6127768aaf96f59be69359e229dacbd2f44f7;p=xboard.git

Fix erasing and exposing of arrow on secondary board

For the second board the damage flags set for exposing a freshly drawn
arrow are left for the next draw to erase that arrow again.
