I think the following change is the culprit.

2008-01-09  Kenichi Handa  <handa@xxxxxxxxxxxxx>

	* coding.c (detect_coding_iso2022): New arg
	latin_extra_code_state.  Allow Latin extra codes only
	when *latin_extra_code_state is nonzero.
	(detect_coding_mask): If there is a NULL byte, detect the encoding
	as UTF-16 or binary.  If Latin extra codes exist, detect the
	encoding as ISO-2022 only when there's no other proper encoding is

I'm now investigating what's wrong.
