Multiple response modes

[Rickard Schoultz <[e-mail]>]

A reply send from a whois++ server has a layout like:

	# response-mode
	 data
	# END

The whois++ document mentions a `Pointer' response mode, allowing the
server to point to another whois++ server (records on another server).
The index document also defines a `Servers-To-Ask' reply, which allows a
server tell the client to pass the query to another server.

It would be very useful if the server could respond with a mix of
response modes. One problem with that is that `# END' is defined as the
end of the response [of the FORMAT response MODE], so this means that we
have to use something else to mark the end of the whole response;
Preferably a system response since that is what we are doing.

A server could in this model yield:

	# FULL
	# USER foo123
	  Name:Grkl Mnpgh
	# END
	# POINTER
	  <some yet-to-be-defined structure>
	# END
	% 226 Transfer complete.

Would that be acceptable?
