The last executed commands are already remembered at different levels,
so the hard task is to decide at what level to turn them to code:

1. at level of complex command execution, such as from the history
   retrieved by `repeat-complex-command` (C-x ESC ESC), for example:

   (rgrep "macro" "* .*" "emacs/lisp/")

2. at level of commands corresponding to all typed keys,
   such as retrieved by `view-lossage` (C-h l),
   for example, for the same as above:

   M-x                ;; execute-extended-command
   r                  ;; self-insert-command
   g                  ;; self-insert-command
   r                  ;; self-insert-command
   <tab>              ;; minibuffer-complete
   <return>           ;; minibuffer-complete-and-exit
   m                  ;; self-insert-command
   a                  ;; self-insert-command
   c                  ;; self-insert-command
   r                  ;; self-insert-command
   o                  ;; self-insert-command
   <return>           ;; exit-minibuffer
   <return>           ;; exit-minibuffer
   <return>           ;; minibuffer-complete-and-exit
