Are you sure? In hostsaddrinfo():

        if (getaddrinfo(name, NULL, &hints, &res0) == 0) {

Which gets called in hosts() after both inet_pton calls return 0:

        if (inet_pton(AF_INET6, argv[i], (void *)addr) > 0)
                he = gethostbyaddr(addr, IN6ADDRSZ, AF_INET6);
        else if (inet_pton(AF_INET, argv[i], (void *)addr) > 0)
                he = gethostbyaddr(addr, INADDRSZ, AF_INET);
        if (he != NULL)
                hostsprint(he);
        else if ((rv = hostsaddrinfo(argv[i])) == RV_NOTFOUND)
                break;
