A tiny bit of repetition makes this easier to read, and avoids a test on the "Not a base prefix" match arm.
After seeing a `0`, if it's followed by any of `[0-9]`, `_`, `.`, `e`, or `E`, we consume all the digits. But in the `.`, `e` and `E` cases this is pointless because we know there aren't any digits.
