Fine with me. I may look at it later when Peter's second patch changing 
this code lands if there are any cleanups possible, I've noticed that now 
that we have xferlen = count * width it could be used elsewehere where 
that product appears for example. At that point I'll see if the type can 
be changed too. Until then it's fine as it is now.
