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.
