Alejandro Colomar 8f134c0bea Use isdigit(3) instead of a reimplementation of it 
C89 defined isdigit as a function that tests for any decimal-digit
character, defining the decimal digits as 0 1 2 3 4 5 6 7 8 9.

I don't own a copy of C89 to check, but check in C17:

7.4.1.5
5.2.1

More specifically:

> In both the source and execution basic character sets, the value
> of each character after 0 in the above list of decimal digits
> shall be one greater than the value of the previous.

And since in ascii(7), the character after '9' is ':', it's highly
unlikely that any implementation will ever accept any
_decimal digit_ other than 0..9.

POSIX simply defers to the ISO C standard.

This is exactly what we wanted from ISDIGIT(c), so just use it.
Non-standard implementations might have been slower or considered
other characters as digits in the past, but let's assume
implementations available today conform to ISO C89.
