Anyone familiar if any tool exists today that would optimize this? Is anyone working on it? Would git be a good place for such a thing? I'd consider it as an option to optimize a diff. This for example is extremely useful for us working with Coccinelle where we have a tool writing code for us, while such an optimization might be useful to Coccinelle it would seem like a rather generic feature, its just not clear to me where to give such a tool a proper home.
