Yeah, screen scraping is just wrong in the principle, at best it can be a

I wanted to propose an option switch that would query the presence of a
target, but what you suggest is a lot more general.
Merely extending the exit code from present "2 for all errors" would be
probably the best idea for something convenient in most cases -- and
machine-parseable output could help when that's not enough.
