	isprint() (and everything else in <ctype.h>) has a fixed table of
	case.  Unfortunately, this does not support ISO 8859-1 or other
	likely character sets.

	This means, for instance, that vi will believe that \xe2 is not a
	printable character, even though it is in that character set.

	This could, if fixed, also make stty lcase's behavior smarter.

	Read isctype.c
	I think the best thing to do would be to make _ctype_ be a pointer,
	not an array, and point it at one of several built in arrays,
	depending on the current locale.  The default behavior would
	presumably be the same.
