Adding expansion is not just "harder". It's basically impossible to do with any kind of performance. Think "git checkout newbranch". And think what we do about files (and whole subdirectories!) that haven't even changed. And finally, think about how important that optimization is in an SCM like git that supports branches. I think you'll find that keyword expansion simply isn't acceptable. But hey, you didn't believe me, so I'm happy you are trying to write the patches. Either you'll prove me wrong, or you'll realize just *how* broken the feature is. (Yeah, "unexpansion" is easy. It's easy for all the same reasons CRLF is easy: it has no state!)
