  isalnum_l, isalpha_l, isascii_l, isblank_l, iscntrl_l, isdigit_l, isgraph_l,
  islower_l, isprint_l, ispunct_l, isspace_l, isupper_l, iswalnum_l,
  iswalpha_l, iswblank_l, iswcntrl_l, iswctype_l, iswdigit_l, iswgraph_l,
  iswlower_l, iswprint_l, iswpunct_l, iswspace_l, iswupper_l, iswxdigit_l,
  isxdigit_l, toascii_l, tolower_l, toupper_l, towctrans_l, towlower_l,
  towupper_l, wctrans_l, wctype_l, strcasecmp_l, strcoll_l, strfmon_l,
  strftime_l, strncasecmp_l, strxfrm_l, wcscasecmp_l, wcscoll_l,
  wcstrncasecmp_l, wcstrxfrm_l, strtod_l, strtof_l, strtol_l, strtold_l,

- locale(1) now supports a -i/--input option to fetch the current input
  locale (this is basically equivalent to the current keyboard layout setting).
