I had to add one rule:
If it starts with a zero, it's always an octal number. Up to two more octal digits are accepted after the leading zero.
but this still fails on this pattern:
r'(a)(b)(c)(d)(e)(f)(g)(h)(i)(j)(k)(l)\119'
where the last part is supposed to be a reference to group 11, followed by a literal '9'.
But 9 isn't an octal digit, so it fits w/ your new rule just fine. \117 here instead would be an octal escape.
