bug#26535: 25.1; `edit-last-kbd-macro': wrong info in comments

[Drew Adams <drew.adams@oracle.com>]

emacs -Q
C-x d RET ; Dired some dir
<f3>
M-x forward-char RET
<f4>
M-x edit-last-kbd-macro RET

Buffer *Edit Macro* shows the wrong bindings for the keys
pressed to define the macro.  It shows Dired bindings for
each key, but those keys were pressed as minibuffer input
for `M-x':

;; Keyboard Macro Editor.  Press C-c C-c to finish; press C-x k RET to cancel.
;; Original keys: M-x f o r w a r d - c h a r RET

Command: last-kbd-macro
Key: none

Macro:

M-x			;; execute-extended-command
f			;; dired-find-file
o			;; dired-find-file-other-window
r			;; self-insert-command
w			;; dired-copy-filename-as-kill
a			;; dired-find-alternate-file
r			;; self-insert-command
d			;; dired-flag-file-deletion
-			;; negative-argument
c			;; dired-do-compress-to
h			;; describe-mode
a			;; dired-find-alternate-file
r			;; self-insert-command
RET			;; dired-find-file

`edit-last-kbd-macro' interprets the macro definition
in the context of whatever buffer is current when it
is called.  If you change to another buffer in the above
recipe before invoking it, the commands shown in the
comments will be completely different (but equally wrong).
