i think that the port range restriction is useful and since adding this
functionality to wget is not very difficult (and if correctly done, it
does not break IPv6 support), we should definitely do it.
however, i am not very happy with turi's code, since the parsing of the
--bind-address argument should not be done in resolve_bind_address
but in the getopt loop and it should not use sscanf.
