According to the document of `recent-keys`, the return value does not
contain
events generated by keyboard macros, but it does.

To reproduce this:
Run Emacs by "emacs -Q",
define a keyboard macro by "<F3> a <F4>" (a keyboard macro that inserts
"a"),
and hit <F4> twice.
I expected the last two items of the return value of recent-keys are F4, F4,
but they are F4, 97.

I used the following code to check it.

(progn
  (require 'cl-lib)
  (defun my/test-recent-keys ()
    (message (prin1-to-string
              (let ((kys (recent-keys)))
                (cl-subseq kys (- (length kys) 2))))))
  (add-hook 'post-command-hook #'my/test-recent-keys))

In Emacs 24.5, the last two items are F4, F4 as expected.
