    Reimplement execute-extended-command in Elisp.
    * src/keyboard.c (Fexecute_extended_command, Vsuggest_key_bindings):
    Move to simple.el.
    * lisp/simple.el (suggest-key-bindings, execute-extended-command):
    Move from keyboard.c.

That looks reasonable given that it touches code closely related to the
