Thanks for the pointer, Graham. I knew that the URI code had
been written a while ago, but never realized how extensive
the changes were! Great job.

Now the only problem is that the module doesn't expose the
functions we would need; such as Network.URI.host, for
instance. Would it be possible to factor those parser out
into a

  Text.ParserCombinators.Parsec.Rfc3986

module? Maybe we could even merge those parsers with the
ones I have here:

  http://cryp.to/hsemail/docs/index.html

RFC grammars are often very similar after all.

P.S.: In the definition

  host = ipLiteral <|> try ipv4address <|> regName

it looks as if the 'try' modifier should be given for the
first alternative; not for the second. I may be wrong
though.
