Redisplays all blanked entities, restoring the selection group.

Description:
This command redisplays on the screen all entities which were temporarily
erased by the \blnk or the \lblnk command.
The original selection group, (which existed when \blnk was executed), is
restored.
NOTE:If you added walls which intersect walls that were not displayed, you may
now have to fix the intersections.
