I've just sent my current set of stable patches for the evolve command to the list. The code should be stable, but there's follow-up stuff I still want to do: - Add more tests for the new code. - Make better use of the memory pool in change-table.c (ideally, all the memory it uses should come from the memory pool). - Cosmetic non-functional touch-ups. I may not have a chance to do more work on evolve for a while, and since others have expressed an interest in helping with this work, building on top of it, or just tinkering with metacommits - I thought it would be good to make the code available to the community.
