RE: [RFC] Refresh iswblank and iswspace (was Re: Update wctype functions to Unicode 5.2?)

Unfortunately, not quite so simple--but almost:
we'd need to check if the locale is exactly either "C" or "POSIX".
(It's a little annoying that POSIX allows either when there is no
apparent difference between them, but it's what they require.)
 
Yes, a <=0x7F check would seem appropriate (similar to the current
non-MB-capable check) when in "C"|"POSIX".
