There's clearly desire for it. Otherwise Lennart wouldn't have created
that wrap fill mode. Screens are getting wider so having lines of 200
chars is painful to read. Would be nice if 'visual-line-mode' gives user
an option to set a maximum width.

Using fringes or margins (now that I have tried it and I can imagine how
Lennart implement his mode) are all workarounds and they are not much
different than opening up a frame with the desired width but then it is
a waste of screen estate and it has impact on productivity.

This is also another workaround, something I have been doing myself for
quite a while now with this tiny function.

(defun adhoc-workspace-setup ()
  (delete-other-windows (get-largest-window))
    (split-window-horizontally (floor (* 0.6 (frame-parameter nil
    (switch-to-buffer-other-window nil t)))

The thing is very easy to lose the setup, C-x 1, switch buffer etc etc.
If I save the setup to a register it also restores the point, something
quite annoying when writing.
