:mrdocs:

Disable this async file observer from using the long output format when logging to `stdout`. Henceforth, this async file observer will use the default short output format ("n%s %f:%l %c %m %un") when logging to `stdout`. This method has no effect if the long output format for `stdout` logging is not enabled. Note that this method omits the "%d %p:%t " prefix from the default long output format. Also note that this method affects records subsequently received through the `publish` method as well as those that are currently on the queue.
