Octal literals, e.g. 'int i = 010;' are arguably evil #227

I just finished swearing up and down that the integer literal 010 would equal ten, not eight. How embarrassing.

If we have managed to get the 'l' suffix error to work, it might be worth considering a check that forbids all octal literals as well.

They're kind of useful when converting between numeric POSIX file permissions and other formats, though I admit that's very much an edge case.

We found many legitimate uses of octal literals for file permissions, and many illegitimate uses for dates. We could possibly special case the checker to allow octal literals that are passed into file-permission-accepting methods.
