Thanks for the reply Wilfred! I was not familiar with Autochrome, I will certainly have a look!

That's interesting, I like the idea of not worrying about patching nor merging, giving you a tool that is focused on "communicating the differences to a human", and indeed, it means you don't have to worry about a whole bag of problems.

One insight that I came across (more info on Chap 5 of my thesis) is that not considering or handling duplication means you incur a quadratic slowdown in your search algorithm. For example, say you're diffing `A` against `Bin A A`. If you can't understand that `A` was duplicated, which `A` do you copy? You have to evaluate both options even though it really doesn't matter which one you copy.

One good middle ground for speeding up your algorithm while not having to worry about displaying duplications is to have an intermediate step where first you diff with duplication detection, but then you just go over the result and make arbitrary choices about which duplicate to copy and which to insert/delete.
