vdef calc was using end_orig to determine for which range it should do its

calculations which is odd, since orig is only the requested range as
invocation time and not the data range deliverd by fetch. It does fall
completely flat when shifting since shifting does not affect the original
data. Bug #177 reported by hokiel
