This was shown to be a problem by side effect of now-enabled test case, which was going through C, en_US.UTF-8, ja_JP.SJIS, and ja_JP.eucJP, and failing eventually as data in mbrtowc's mbstate, that was perfectly correct for en_US.UTF-8 was treated as incorrect for ja_JP.SJIS, failing the entire test case. This makes the persistent mbstates to be per ctype-component, and not per-locale so we could easily reset the mbstates when only LC_CTYPE is changed.
