My understanding is that window-list considers windows on a given frame, 
and window-list-1 considers windows on all frames (unless it is asked to 
consider only a given frame).

If you want to allow the argument t to window-list to mean "all frames", 
you probably also want to allow the symbol 'visible and the number 0, 
which are accepted by window-list-1... and in that case window-list and 
window-list-1 become basically the same function.
