Subject: [PATCH] fix for bug #27826: fixed autoDisplayComment

apparently the -autoDisplayComment option was not working,
not even in WinBoard. This patch should fix it,both for WB and XB.
(Unfortunately xboard.c and winboard.c were using a different name
for the same front-end variable I needed, so I had to change one of them.)
