>(NeXT may have changed this, but I seriously doubt it)

     That is correct.  NeXT did not change it.  Your misunderstanding is
due to your familiarity with the SysV cron and not the BSD cron.  The BSD
cron uses the form he showed.  It uses a loginid field preceding the
command.  The loginid field obviates the use of su(1) before the command.
Note also that the BSD su(1) differs substantially from the SysV su(1).
