Hello,

I know there has been much discussion on the completion mechanism
recently, but (or "hence" ?) I didn't find a bug report specifically on
this :

From emacs -Q:

M-x ibuffer RET
m
E
em-ve TAB

At this point, earlier versions expanded em-ve to emacs-version (a
variable), but the latest ones don't.

--

I'm trying to understand why : I noticed that E in ibuffer does this:
    (read-from-minibuffer
     "Eval in buffers (form): "
     nil read-expression-map t 'read-expression-history)
whereas M-: does this:
    (read--expression "Eval: ")
and the function read--expression changes 'completion-at-point-functions in a
minibuffer hook.

Note that read-expression-map used to have the following docstring:
"Minibuffer keymap used for reading Lisp expressions.". That was changed
[on Sat May 4 15:27:41 2013 -0400 -- commit f7d4dcf]. The same change
moved the actual definition from C to simple.el but the comment stating
"It is defined at C level." remained in simple.el.

I think I've now fixed this in Emacs 27 by just making that command call
`read--expression'.
