Good idea on using `--fail` @grooverdan 

The blocklist.de returns a text with "status: success" or "status: error", but always code _200_.  My inverse on the return was such that the "error" could be matched so it would be logged.

@blocklist Could the blocklist.de API be changed to returned a [HTTP 4xx status](http://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error) along with an error?

I'd agree that having a version substitution would be cleaner for _0.9_
