- * ISDIGIT differs from isdigit, as follows:
- * - Its arg may be any int or unsigned int; it need not be an unsigned char
- *   or EOF.
- * - It's typically faster.
- * POSIX says that only '0' through '9' are digits.  Prefer ISDIGIT to
- * isdigit unless it's important to use the locale's definition
- * of "digit" even when the host does not conform to POSIX.
