Add comments explaining the purpose of B-Tree support function 5 to nbtree.h for consistency (all other support functions were already described by nearby comments). This fixes what was arguably an oversight in commit911e702077, or in follow-up doc commit15cb2bd2(which documented support function 5 in btree.sgml, but neglected to add anything to nbtree.h).
