yet another "trunc*" bug fixed - and the fundamental one! (now, when next trunc* word is less than curdoc it doesn't led to wrong results)

fix for a nasty bag, that causes a memory corruption+crash on HUGE select distincts, as myisam temp table treats nulls as equal, it constantly returned 141 (duplicate key) error in create_myisam_from_heap
