I regularly use at least cat, wc and od this way (plus a few of my own
utilities like utf8dump). I'm sure I've used sort this way, too, though
rather rarely. I usually don't type the input but paste it in, but the
program can't distinguish that: All it sees is some input from the
terminal at stdin.
