Hmm... why is this particular command (M-:) being singled out? We
have a uniform behavior of "C-x ESC ESC" with all the commands: they
are stored and displayed as the equivalent Lisp expressions. E.g.:
C-x C-f ~/foo/bar RET
C-x ESC ESC
-| Redo: (find-file "~/foo/bar" t)
or even
M-x set-variable RET auto-hscroll-mode RER current-line RET
Cx ESC ESC
-| Redo: (set-variable (quote auto-hscroll-mode) (quote current-line) nil)
Moreover, "M-x list-command-history" also shows the above expanded
forms.
One could argue whether showing Lisp instead of something similar to
what the user actually typed is a good idea, whether it's educational
or not, but this is very old and consistent behavior. If we are going
to change that, I think the change should affect more than just M-:,
and should probably be an optional feature.
