`uname &' and `>/dev/null' should be parsed as two separate commands;
that, if I'm not missing anything, is what POSIX says. But bash
doesn't do that in POSIX mode, and redirects both stderr and stdout to
`/dev/null'.
You're right, and it's not worth changing at this point. It's come up
before, and the bash interpretation is much more useful and compatible.
