  * improve efficiency of annotate
  
  The patch index makes finding the relevant patches quite efficient,
but when
  a patch contains many hunks, the previous implementation took a very long
  time to finish. This was because it naively applied every hunk and
then used
  diff to see which lines were changed.
  
  The new implementation directly observes the effect of patches on the
  Annotated structure using the new Annotate patch interface (type class).
  This also makes attribution of lines to patches more accurate, since the
  result no longer depends on the diff algorithm that annotate used
  internally.
