Introduce EXIT_BADARGS (129) error code to return, when the user passes
an invalid list of arguments. Currently, we return exit 1 which refers
to a general error, or exit -1 which wraps to 255, both codes do not
signify bad arguments. Let's use EXIT_BADARGS (exit code 129), from
tools hinting to the users about invalid usage.
