Okay, CVS code now supports the following two incantations in the 
2nd-10th lines of Perl plugins:

# nagios:+epn

# nagios:-epn


Its probably better to cache the plugin directives as you mentioned, so 
I'll take a look at doing that.  Although I can see it would be useful 
to allow people to tweak plugin directives without having to restart Nagios.
