-This patch skips all tests related to PTYs: they all fail under portage
-because we don't have a valid TTY. Skip them. A bing chunk of them are
-skipped through "skipper()" under mock_pty. The rest of them are skipped
-by simulation windows (tests that don't run under windows don't run under
-portage either).
