It is ("reaching the } that terminates the main function returns a
value of 0" - C99 5.1.2.2.3 #1), but testing with "echo $?" (even when
that works, which will depend on the shell in use) doesn't demonstrate
anything about guarantees, only about what happens in the particular
environment the test was run in.
