Introducing a wrap-column variable is almost exactly the same as
changing the window width, or equivalently the right fringe width.  I
don't see the advantage in further complicating this part of the code to
introduce a new way to do the same thing.

It would be easier, for example, to introduce a separate patch that
automatically adjusts the right fringe so that the editable area has a
certain width.

I don't know what this is about.
