The code will rip out easily enough, it is (almost) under a
conditional compilation already.

It might? be worth including print (aka ksh), you don't always want
the complexity of printf (esp. since is isn't a builtin).

The man page ought to list the builtins, there are some subtle
differences.  eg what happens when a redirect fails (not checked
that on netbsd - you need a device driver that rejects opens).
