I think exit(0) is required to turn into whatever the OS's success
indication is.

Whether EXIT_* are more readable is a matter of opinion; I find them
less readable, actually.  (Not that I'm any great fan of
/usr/share/misc/style, mind you; quite a number of the things it calls
for impair readability for me.)
