This is with the latest trunk emacs.

In *shell* buffer, if I have files temp1, temp2, temp.txt,
and type as this (<TAB> means the TAB key):

    % rm temp<TAB>

*Completions* buffer pops up and lists temp1, temp2,
temp.txt.  But after that, when I type '?' key, ? is not
inserted in the buffer because C-h c ? tells that it runs
completion-help-at-point.  This is very annoying.  What I
want to do is to delete only temp1 and temp2 by typing "rm
temp?".

It's not a bug it's a feature.
You can use `C-q ?' of course.

Ah, that's what "the standard completion UI" in NEWS means.
Ummm, I don't like it.  What annoys me most is that it's
very difficult to find when '?' is bound to
completion-help-at-point.  Are there any easy way to
customize Emacs not to bind '?' to completion-help-at-point?

You can remove the binding from completion-in-region-mode-map.

Thank you.  I now have this in my .emacs.

;; To avoid '?' run completion-help-at-point in *shell* buffer.

Shouldn't Shell Mode and its derivatives remap that to M-? or some
such?  `?' is too frequent a character in command-line interfaces to
have it bound to anything other than self-insert-command, IMO.  At
least both Bash and GDB bind that function to M-?, and I think Emacs
should follow suit.

FWIW - `M-?' is what Icicles uses for (minibuffer) completion help.

I think it's nuts that vanilla Emacs still uses ordinary, printing chars such as
`?' and `newline' for special minibuffer commands, instead of just inserting
them.  And even `SPC' outside of (finally!) file names.  A user is more likely
to expect `?' to self-insert than to think s?he should use `C-q ?' to insert a
`?'.

Yes, I know you've heard it before...  But glad to hear Eli in favor of `M-?'
here.

Good point.  I guess completion-in-region-mode-map should use M-? rather
than ?.  Please make this change for 24.1.
