  maint: add coding cookies to non-ASCII sources
  
  Otherwise, Emacs might do the wrong thing if run in an
  he_IL.ISO-8859-8 locale, which an Emacs developer does on occasion.
  Problem reported by Eli Zaretskii in:
  http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00966.html
  
  Don't bother with test files, as they aren't copied to the Emacs
  source directory.  If this problem affects test files in some other
  GNU project, we can add coding cookies to the non-ASCII test files
  later.

  /* Parse the initial portion of the string pointed to by NPTR as a floating-
     point number (in decimal or hexadecimal notation), like in the C locale:
     accepting only the ASCII digits '0'..'9', and only '.' as decimal point
     character.
     If ENDPTR is not NULL, set *ENDPTR to point to the first byte beyond the
     parsed number or to NPTR if the string does not start with a parsable
     number.
     Return value:
     - If successful, return the value as a double or 'long double',
       respectively, and don't modify errno.
     - In case of overflow, return ±HUGE_VAL or ±HUGE_VALL, respectively, and
       set errno to ERANGE.
     - In case of underflow, return a value very near to 0 and set errno to
       ERANGE.
     - If the string does not start with a number at all, return 0 (and recall
       that if ENDPTR != NULL, *ENDPTR is set to NPTR), and maybe set errno to
       EINVAL.
     - In case of other error, return 0 and set errno, for example to ENOMEM.  */
