Debian's which hunt

I've never understood the total obsession some people have with making programs worse just so that they can fit inside the POSIX hairshirt. That's ridiculous. Why would we do that? Instead of changing every program on Earth to avoid which(1) because it's not The Standard, just change POSIX to reflect the reality we already inhabit and standardize the behavior of which(1).

The POSIX standard was not inscribed on stone tablets delivered to us from the summit of Mount Sinai. POSIX is made by humans to accomplish useful goals. We can change it!
