This only works if your "su" supports "-c".  I think that was a System III
addition.

I don't think he's a Berkeley site; it's difficult to install a UNIX system
on a person :-).  If he's running at a 4.3BSD site (or probably 4.2BSD; the
machine with our 4.2 archival source is being cranky, so I can't check),
"cron" is running as root.  (Sun's version runs "cron" as "root", so it was
probably that way in 4.2BSD also.)  I don't remember what V7 did; it may
very well have run "cron" as "daemon" or something like that.
