It depends on what behavior you want, but if "b" is what you want, I think
it breaks existing use cases too much that it should be opt-in.

Two things I think we would need consensus on:

Ah, understood, so you want this behavior only when overflow occurs. That
was then my misunderstanding, sorry about that.

But then this gets even harder to understand for me...so if you have:
AA_AA_A
assume "_" is a space and the width is 5, you want:
AA_AA_
A
(the trailing space of the 1st line overflows)

but if you have:
AAAAA_A
you want:
AAAAA
_A
(the space wraps)?

It looks like it's different from the use case I had in mind. Can you
explain why you want different behavior for the two examples above? Sorry
if this was done before and I missed, but NY resolution does not give this
behavior so I'm a bit confused.
