If there is really a big interest in this I would suggest a Nagios macro
that change based on the Nagios version and then future Nagios-plugins
version could add a standard parameter for receiving the version string.
The version string would be standardized so that on newer strings we
could just use the most recent behavior (in case it's not the default).

I don't thinks this would be really useful unless there's plans for
adding more features or supporting different formats in the future. As
long as we want to keep the plugin output simple I'd just add a standard
switch for multi-line output (that would eventually be removed once
nagios 2 becomes deprecated).
