The setting of LC_CTYPE acts like a catalyst for wcsftime() to
work safely.

I checked the code around the patch and found the central function
cache_locale_time() is rarely called (at most once per LC_TIME change).
The function cache_locale_time() calls strftime() only 38(=7*2+12*2)
times. Now I fundamentally agree with Itagaki-san's patch. Though
it may not be the most effective code, it looks like the clearest one.
