* Fix checked mode exception when _getSocketType returns an OSError * Treat any character device as terminal (this includes /dev/null) * Fix detecting of file redirection af file * Don't turn an unkonwn device type into an OSError (wth value for an unknown was -1) Expanded an existing test to catch some of this.
