Space and non-ASCII keys with a Korean or Telex syllable pending were
committed as text along with the syllable, while '.', ',' and digits
committed the syllable and passed on: one path for both now, through the
language's own trans, which commits and passes on. Japanese Space is
its own key already.
dictqjp() knows which languages have candidates; its two callers no
longer choose between it and clearkouho(). Every request carries its
owner's caret as the frontend knows it, so a Keypress copies it whether
valid or not, and the XIM frontend need not send a Keycaret to say that
its spot went away.
