Well, not really. There is no need for a trailing dot for a
domain name to be fully qualified. The "example.com" domain _is_
fully qualified. The trailing dot is just used by some software to
indicate fully qualified names.

It looks like it's something specifically mentioned by RFC 3986
though, http://tools.ietf.org/html/rfc3986#section-3.2.2:

The rightmost domain
label of a fully qualified domain name in DNS may be followed by a
single "." and should be if it is necessary to distinguish between
the complete domain name and some local domain.

So we probably should support it.
