Since some servers are not regularly upgraded to the latest level (there
are servers which are still running at level 1.3c), I have found very
often necessary to use the HELP command only to determine the version
they are running. This is wasteful in terms of message traffic, but
the command is required to avoid sending commands to a server that it
cannot support.
I think that a 'Help Version' (or somesuch) command would be useful
for that purpose; the only thing to do is to stop message sending
after the version number has been displayed.
