Why? It can be compatible with the standard, but we should call it with base
10 from zzlex.

Bash version 1.14.3 always treat 010 az octal and 0xff as hex in math, and it
segfaults on echo $[09] (at least with Solaris 2.3) :-). ksh ignores leading
zeros. I see that interpreting 0xff as hex but 010 as decimal is not too
elegant, but it does not hurt anyone. The alternative is to give unballanced
stack error on 0xff and if I have to choose I'd choose 0xff to be a hex
number. It can be done in zzlex.
