Ah, thank you! I was unaware of the exit-status constants in ‘os’::

    The following exit codes are defined and can be used with _exit(),
    although they are not required. These are typically used for system
    programs written in Python […]

    <URL:https://docs.python.org/3/library/os.html#os._exit>

That defines a whole lot of exit status values with mnemonic names. I
will try to make use of those instead of re-inventing them.
