I could either:
    1) create one large patch doing many thing (2+3 or 2+3+4)
 or
    2) add the 'offset' parameter with some other name first and rename it 
       to its final name after local var 'offset' is eliminated by patch 4
 or
    3) rename local var 'offset' first out of the way so that I can add 
       'offset' parameter in patch 3 (=this patch)

If I just drop patch 2 and only do 3, it won't build because 'offset' 
variable appears twice (as arg and local var).
