This wiki chunk matches arbitrary URIs, using patterns from the Ruby URI modules. It parses out a variety of fields that could be used by formats to format the links in various ways (shortening domain names, hiding email addresses) It matches email addresses and host.com.au domains without schemes (http://) but adds these on as required.

The heuristic used to match a URI is designed to err on the side of caution. That is, it is more likely to not autolink a URI than it is to accidently autolink something that is not a URI. The reason behind this is it is easier to force a URI link by prefixing 'http://' to it than it is to escape and incorrectly marked up non-URI.
