Well, RFC 3986 (URI) explicitly allows the final dot.  See the section
on reg-name in section 3.2.2.  Sometimes this RFC is used as one of
the example sowers-of-confusion, because despite the fact that the
relevant section is talking about DNS domain names, the name of the
segment of the URI is called "host", and hostnames don't have a
trailing dot.

It's no wonder people who merely have to implement this stuff are
confused, when the stnadards development organization in question
can't figure out how the terminology works!
