http://$ makes my Sopel puke with errors.

Maybe a bug?

...
[11:49am] <Ant> http://$
11:49AM <URL> requests.exceptions.ConnectionError: HTTPConnectionPool(host='$',
          port=80): Max retries exceeded with url: / (Caused by
          NewConnectionError('<requests.packages.urllib3.connection.HTTPConnection

[11:49am] <Ant> haha
[11:49am] <Ant> http://
[11:49am] <Ant> That's a bug.
11:50AM <R_Daneel> not necessarily
[11:50am] <Ant> He shouldn't puke!
11:50AM <R_Daneel> it's just he doesn't know how to handle string functions.
[11:51am] <Ant> We'll see what Sopel developers say!
11:51AM <R_Daneel> it's a lack of a feature, rather than a bug.
...

Thank you in advance. :)
