Fix /[\8]/ to not match NULL; give correct warning
8 and 9 are not treated as alphas in parsing as opposed to illegal
octals.
This also adds tests to verify that 1-3 digits work in char classes.
I created an isOCTAL macro in case that lookup gets moved to a bit
field, as I plan to do later, for speed.
