Elbereth on unoccupied locations

Pat recently forwarded a discussion that Elbereth was ignored unless there
was an object on its location.  Mostly.  It was also respected if the hero
was Displaced, no matter where the hero was.  No one commented on his
message, which I took for assent to address this.  Removed the qualifiers, so
now Elbereth is always respected, just like a scroll of scare monster.
