Non-breaking space missing from iswspace() and iswblank()

[Andy Koppe <andy dot koppe at gmail dot com>]

The iswspace and iswblank don't currently consider the "non-breaking
space" character U+00A0 as a space.

Test:
#include <ctype.h>
#include <wctype.h>
#include <locale.h>

int main(void) {
  puts(setlocale(LC_CTYPE, "en.ISO-8859-1") ?: "C");
  printf("isspace(0xA0)  == %i\n", isspace(0xA0));
  printf("iswspace(0xA0) == %i\n", iswspace(0xA0));
  printf("isblank(0xA0)  == %i\n", isblank(0xA0));
  printf("iswblank(0xA0) == %i\n", iswblank(0xA0));
  return 0;
}

Output:
isspace(0xA0)  == 8
iswspace(0xA0) == 0
isblank(0xA0)  == 1
iswblank(0xA0) == 0

Patch attached.

Regards,
Andy
