Say what I actually got wrong, instead of trying to save face...

@chux, thanks for the correction. And you're right about unsigned char - I mistakenly thought that CHAR_BIT could be 7, (giving 5 chars in 36-bit hardware), but it actually must be 8 or more. I did originally use char, forgetting it needed to briefly represent values more than 99. That's a definite bug, and I did fix that before posting.

Correction - we can't safely add to a null pointer. Thanks to chux for pointing that out.

How is this true: "unsigned char wasn't portable enough to represent up to 198"? If uint8_t works, certainly unsigned char works.

digit *end = d + digits; should occur after if (!d) {...}
