Ah, shoot, I'm a bonehead.  Of course it works fine.  This is just a
ksh93 bug and/or misfeature.

In /sbin/sh:

	$ set -- `/bin/false`
	$ echo $?
	255
	$ set -- `/bin/true`
	$ echo $?
	0
	$ 

In ksh88:

	$ set -- `/bin/false`
	$ echo $?
	255
	$ set -- `/bin/true`
	$ echo $?
	0
	$ 

In ksh93, it appears that this third case actually returns the
argument count rather than 0 for success.
