Using Emacs on this file is pretty much impossible due to the super-sluggish behavior. It's embarrassing. Why is this? Can it be fixed? This is with fundamental-mode, by the way. `forward-char' and `backward-char' are pretty much the only usable commands, even "C-h f" (describe-function) is extremely slow in this scenario. -- Deniz Dogan
