This is presumably because there currently is only one suffix that uses the
`DoubleUnderscore` flag, so the other flags that also get set when `__wb` is
parsed (e.g. `HasSize`) would be enough to disallow repetition here, from what
I can tell. I’d still keep `DoubleUnderscore` in case we decide to add more
literal suffixes that contain double underscores.
