An alternative could be to change the outer if condition to exclude n == NULL, but I didn't do that because the change of job_warning and clearing of numeof make sense to me even for null commands. Besides, when debug tracing is enabled, null commands have a visible effect that should remain. Note that this fixes the problem with . but the same problem can be present in other locations.
