As you say, these settings are inconsistent. Zile doesn't use terminfo or 
stty directly; it uses ncurses. I've tried to get down and dirty with 
terminfo before but it only caused more problems than it solved, so I don't 
want to follow that route again.

I am however interested in eradicating the underlying bug here, if it still 
exists, so that in future Zile users will be less likely to run into it.

I'd be most grateful if you could shed any further light on this.

I fear that this way lies only pain, especially in trying to hack around 
ncurses. Suggestions welcome, as usual.
