OK, that's fair. So, if I understand you right then, I will redo the
changes and anywhere that is might not be already (unsigned char), you
would suggest that I called it like this for example then and the
results would be the same as it is now using the ap_isdigit() one.

If *r->range is not already (unsigned char), then cast it

so:
if (isdigit((unsigned char)*r->range))
instead of:
if (isdigit(*r->range))
if apply here.

So if already (unsigned char), then obviously leave it alone.

Do I understand you properly?

We can also take that off list if everyone else already understand this
and I am just thick. I don't want to waist anyone times.

Thanks for your feedback.
