I'm not sure I understand this objection.  In count-from-end mode, f0 is not 
defined by the user.  It is set as a function of the requested number of 
frames.  As such, it will necessarilly exist on the skip boundary as it is 
the first frame.

What I suppose you are saying is that when in count-from-end mode that we 
should divide up the frames beginning at the start of the file and then count 
back from the end the requested length and find the frame closest that lies 
on the skip boundary.

What I am supposing (and the patch is doing) is that when in count-from-end 
mode that we count back from the end the requested length and the frame we 
arrive at is then f0.  We then divide up the length according to skip.

Where do you see this?  From what I see, it only updates every SKIP frames.
