The Unix tradition, fading away like all the other Unix traditions, is that
exit code 0 is for success, 1 is for failed execution, and 2 is for
reporting that the usage was incorrect, preventing it from running.
Although one could make the case that "-help" did what it was supposed to
do, tradition
It's reasonable to consider calling a command with a flag that is not
defined an error (whether that flag is -help or -verbose or -whatever). It
is common to return non 0 on error.
