Neat idea.
I don't have time for it just now though, so unless someone else steps
in, this will have to wait. If you can't do it yourself, or pay someone
to do it for you, I'd suggest you get an account at tracker.nagios.org
and submit this as a feature-request.
Since it's already possible to do with a fairly easy workaround, it
probably won't get a high priority though, but it might be fun as an
exercise for someone who wants to try out their programming wings.

Yes. Look in get_raw_command_line_r() and add your 30-40 lines of code there.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
