That said, which(1) has similarly non-standard output on other
platforms. But indeed the reason I originally wrote the which(1) that
ended up in debianutils is exactly that I was fed up of unparseable
output and wanted something coherent. It'd be a great shame to drop it
and thereby no longer have something we can rely on at least in Debian.
(Not to mention that reshuffling tools just for the sake of it is a
pain.)
