hanjaquery was the only query that assigned dictprefix's output straight
into im.kouho; emojiquery, dictqjp and katakouho all go through
addkouho, which is the only place a duplicate is dropped. Two readings

two-syllable prefixes in hanja.dict do: 게 listed 偈句 at rows 8 and 9,
개근 listed 皆勤狀 twice in five.
