Given modern branch prediction and instruction caches, I wouldn't be surprised if removing the special cases in keyboard.c for self-insert- command, forward-char, backward-char were itself an optimization. It'd also have the nice effect of making these commands behave normally for advice, redefinition, debugging, and so on.
