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.
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.
