Seems logical. But if it does so, shouldn't it turn it back on then  
(i.e. to the previous value) when it's deactivated?
At least when text-mode-auto-fill is on...

In addition to what David K suggested, it might be possible to just  
wrap the text to the smallest of all window widths. That's not the  
ideal solution, but still better than just wrapping all text to some  
arbitrarily predefined line length by default.

By the way: longlines-mode (with longlines-wrap-follows-window-size)  
seems to wrap to early when using a variable-width font. Since  
variable-width fonts are predominantly used in text (as opposed to  
code) writing contexts, and that's where longlines-mode plays an  
important role, it might be a good idea to think about a fix.
