Such algorithm finds closest pair of (Lpos, Rpos) but satisfying pair could be
not closest, example: to_tsvector('simple', '1 2 1 2') @@ '1 <3> 2';


Oh ... the indexes in the lists don't have much to do with the distances,
do they.  OK, maybe it's not quite as easy as I was thinking.  I'm
okay with the patch as presented.
