I applied the first and last. The change to use read_pending I didn't
apply, since that's a function that shouldn't have been exported in
the first place, since it's usually incorrect to use it. In this case
it would be safe, until someone decides to add the feature of
automatically detecting renames. You're welcome to try to create a
safe and efficient interface for examining a subset of the local
changes, but until then I don't think it's the end of the world for
darcs changes to be as slow as darcs whatsnew.
Note that a very nice improvment for this would be to introduce a
mechanism for obtaining the changes to just a subset of files,
