Making the change or making the change only for whitespace? Either way, I don't see why the width would make a difference.

Try it with a positive width - same thing. Again, hl-line boxing is hardly typical, I think (again, not at all typical for my use, at least). More typical is boxing a word or two. And one could even argue that that jerkiness was a feature (!) for hl-line mode. Anyway, hl-line mode should not be important to this - boxing is for many more use cases than that. > > Would it be possible for this to be a user choice? > > It's possible. That I would be in favor of. Simply changing the behavior/appearance without user choice, I would be against. Again, just one opinion, of course.
