Subject: Improve -showTargetSquares on click-click moves
X-Git-Url: http://winboard.nl/cgi-bin?a=commitdiff_plain;h=fd1000efa5cb589e1446a4e1cfb0b4d222b0f65d;p=xboard.git

Improve -showTargetSquares on click-click moves

The markers on move targets are now kept when a first click merely
selects a piece, rather than dragging it elsewhere. The second click
(by definition on the to-square) then clears the markers.
