Disable this file observer from using the long output format when logging to stdout. Henceforth, this 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.
