You should still be able to check a fair number of things. This isn't like the curses GUI, where there's the curses library sitting between our code and the terminal. All of the escape codes we print are fully within our control.

For example, it should be possible to check that the right escape sequence for enabling/disabling the status line is printed in response to changing the setting value.
