Comment 2 for bug 700878

Yes, what I'd /expected/ to happen is that annotations would be shown for all the lines that changed in that range, with other lines blank... but I was going to the "minimal intervention" approach. I'm perfectly fine that this wouldn't be suitable for bzr-as-a-low-level-tool, but it would be useful functionality if bzr were to transition to focus on higher-level primitives.

If there is scope for looking at range-handling more generally then it might be possible to break that range handling out so that it works more consistently (eg. at the moment 'bzr log -r B..B' returns that matching 'bzr diff -r A..B' whereas 'bzr diff -r A..A' errors).
