ERANGE
This is not checking a range but making sure it is not bigger then 8.
IMO I would use ERANGE if the check was a boundary check for upper and
lower bounds.
Yeah, ERANGE is not perfect, but the strerror for E2BIG is
"Argument list too long" - IDK if users seeing that will know that it
means the value is too large. Perhaps we should stick to EINVAL?
EINVAL works for me to.
