analogous to longlines-wrap-follows-window-size.

The following does the job for me:

(add-hook 'window-size-change-functions
          (defun follow-size (frame)
            (set-window-wrap-column nil (window-width) t)))


I would imagine this "follow window size" mode is how most people  
would use it.
One could allow for something like

(set-window-wrap-column nil 'window-width t)

to indicate that lines should end at the maximal length in the  
window, whatever that is.

You're right. Works like a charm!

OK, but how to keep track of the horizontal cursor position?
The current previous-line and friends (actually, line-move-1) doesn't  
really work well for variable-width fonts, because it always tries to  
jump to the same character position, which can be far to the left or  
to the right. For example, position the cursor at the end of line 1  
in the following example, then go down.

1: iiiiiiiiii*
2: OOOOOOOOOO*

You end up at the end of line 2, and not after the 4th or 5th O, as  
you would expect in a variable-width font setting.

By the way, I just noticed that with window-wrap-column turned on  
(and not wrapping anything in the above two lines), I cannot jump  
down from 1 to 2 - the point always ends up in the line afterwards.  
Let me know if I should investigate further in case you can't reproduce.
