The {a..b} construct isn't portable: this needs to be runnable with
a plain Bourne shell like /bin/dash.
I think we should use the same wordlist technique as check_p_numbers[0-6].
So I guess the first step would be to rename check_p_numbers[0-6] to
something more general and use it both here and in check_p_numbers.
Thanks,
