    (setq zero-input-auto-fix-dot-between-numbers nil)

- bugfix: should call (zero-input-pinyin-register-im) once when the code
  is moved into a function.

- bugfix on zero-input-pinyin: sometimes after GetCandidate dbus call,
  zero-input-fetch-size and zero-input-candidates is not updated. This
  was because the async function callback didn't update the metadata in
  some places.
- zero pinyin supports sync and async mode.
  to switch between them, run
  M-x zero-input-pinyin-enable-async
  M-x zero-input-pinyin-disable-async

support space char in full-width mode.
