I understand, it's indeed quite cryptic to understand. But all
the diff algorithms (patience, minimal, histogram, myers) give
the same result. I don't know how to make it better.

I could split this patch, but this also means breaking tm2's
functionality, which looks worse.

Please tell me if you know a better way for generating the patch.

Thanks,
Andi
