Add tests for some other command line option invocations. Some more of the invocations are tested in this change: - bad switches - errors in configuration files - regular command, configuration and init command ordering - persistence of variables over command invocation. - interactive and login switch use - terminal exit code return - version request There are sure to be other invocations that should be tested, but these give a fair number of them a go. 2017-06-29 23:37:55 +08:00			`-c 'if status --is-login ; echo login shell ; else ; echo not login shell ; end'`
