    The pardon is governed by Xorriso_option_abort_on() and by the anger
    of the affected program part. If no pardon has been given, then the problem
    status reaches the caller of option functions.

    reset before next option execution by Xorriso_set_problem_status().
    The problem status itself does not cause the failure of option functions.

    status can cause overly harsh program reactions.
