IMO, no. It doesn't now, and it's too easy to generate false warnings.
I also think it's very less likely to make a hexadecimal-instead-of-octal
error, then a digital-instead-of-octal error. After all, for most people
digital is what they've learned early in life. As Nick said, warning on
\08 makes sense, as it may happen because someone added 1 to \07, forgetting
about the octal issue. 

Heck, we don't even warn (and we shouldn't start now, I may add) on /\xabc/.
