UNIX diff does this (I remember recently a comment pertaining to the exit-code).
Some other utilities document the exit codes (I don't remember offhand).

VMS uses a wide variety of exit codes (with the opposite sense of 1/0).
Of course MS-DOS does this (it's part of the documentation).

But the usual (portable) practice is 0 (EXIT_SUCCESS) and 1 (EXIT_FAILURE).
