        Make whatis/apropos only display any given manual page, or pointers
        to it, once (Ubuntu bug #27113).

        * lib/hashtable.c (hash_lookup_structure): Make external.
        * lib/hashtable.h (hash_lookup_structure): Add prototype.
        * src/whatis.c (get_whatis): Split pointer resolution out to ...
          (resolve_pointers): ... here. Only accept info->pointer == page if
          info->name == page too.
          (display): Use resolve_pointers so that we have the resolved name
          to hand. Only display any given resolved name once.
          (main): Initialise display_seen hash table.
        * docs/NEWS: Document this.
