    Re-highlight windows when needed during TUI startup
    
    I noticed that "tui enable" did not correctly show the source window
    as having the focus.  Debugging showed that the problem was that
    tui_update_variables was called after the windows were drawn, and its
    result was being ignored.  This changed the code to re-highlight the
    windows if the value changed.
