Patch for 210892

It looks like this is a side effect from a fix for a redirect bug. The fix was
introduced in commit 3389187e4b646b62f4754a92855389d967de816f (in the github
repo).

The original problem was whois didn't follow certain redirects correctly, and
wouldn't give accurate information (the U of M example).

There was a possible loop with APNIC however. The response from APNIC for the
IP in this bug report would match the ERX-NETBLOCK, be redirected to ARIN,
which would then redirect back to APNIC.

I've proposed a patch which fixes the problem. But I'm not too familiar with
the intricacies of the whois system. The original author probably has much more
insight as to whether this solution is acceptable.
