From: Chen Gang <[email protected]> 'writeconfig' supports output to stdout (with '-'); when that happens, we must not close stdout, or further command line options that also use stdout will be impacted. (Although 'writeconfig' was copied from 'readconfig', the latter does not have the problem because it does not support reading from '-')
