if there's a /path after the host, don't add /lookup here

This hit me. Please document it. Or just always set to /lookup?

/* if there's a /path after the host, don't add /lookup here. */
x = 0;
for (p = dnsdb_server; *p != '\0'; p++)
x += (*p == '/');
lookup = (x < 3) ? "/lookup" : "";

some dnsdb server prefixes have a path. so, the default path is /lookup, but won't be add any path at all if one was specified as part of the server spec.
