Hello.

A small bug report from me. I have actually 3. here is 1st one.
(I am not sure where to send bug reports, as there is 3 places with
libwww-perl issue lists)

In the docs for LWP::UserAgent there is:

> There will still be a response object returned when LWP can't connect to the 
> server specified in the URL or when other failures in protocol handlers 
> occur. These internal responses use the standard HTTP status codes, so the 
> responses can't be differentiated by testing the response status code alone. 
> Error responses that LWP generates internally will have the "Client-Warning" 
> header set to the value "Internal response". If you need to differentiate 
> these internal responses from responses that a remote server actually 
> generates, you need to test this header value.



However this does not work when you set max_redirects to 0.

I am getting the following:

> 500 Can't connect to 1.2.3.4:443 (Connection timed out)
> Content-Type: text/plain
> Client-Date: Sat, 03 Nov 2012 14:32:56 GMT
> Client-Warning: Redirect loop detected (max_redirect = 0)


(Client-Warning overwrited with another message about redirect loop)

so I think this should be noticed in documentation, at least.
