That should be doable, yes.

I just can't think of another mode that does something similar. So this 
kind of special behavior might catch people by surprise.

Anyway, this is not a strong objection, and I might be convinced by a 
particular implementation. We could even adopt this practice in more 
places, if it really makes sense to people.

At the moment, though, I'm more in favor of adding a *-global-modes 
variable, and then, having collected feedback, changing its default in 
some future version.
