Cleaner, avoid these files in home directory:
,----
| (defun run-autosave-in-scratch ()
| (with-current-buffer "*scratch*"
| (make-auto-save-file-name)
| (auto-save-mode 1)
| (setq buffer-auto-save-file-name "~/.scratch-autosave/scratch.el")))
`----
`buffer-auto-save-file-name' will become buffer local variable.
