Hmm... hooking at InterTree.iter_changes fails to catch all cases unfortunately (for example bzr diffing between current state and last revision uses InterDirStateTree instead). We probably need to hook at a higher level, like merging entries coming from extra iterators (that our hook would provide) directly in DiffTree._show_diff.
