Hi, 

I'm trying to make use of ido style completion in Info-mode.
Specifically, when `m'(namely, M-x Info-menu) in info buffer, I'd like
it to do completion in ido's style.  

The relevant codes seems in info.el: 

,----[ Info-menu ]
| (completing-read (if default
|                      (format "Menu item (default %s): "
|                              default)
|                    "Menu item: ")
|                  'Info-complete-menu-item nil t)
`----

I'm thinking that I need to replace completing-read with
ido-completing-read.  I have read docstring of completing-read, but
still can't figure it out how does it work when `collection' is
function, in here, 'Info-complete-menu-buffer.

Any hints?

It would be best if a new customizable option called
`Info-completing-read-function' were defined, with 'completing-read as
its default value.  Then the code could just do:

  (funcall Info-completing-read-function ...)

I do this in all of the Emacs Lisp code I touch which uses
completing-read.

I think it would be better to create a new `completing-read-function'
variable like already existing `read-file-name-function' and
`read-buffer-function'.

Yeah, that sounds nice.  

Even better, if only there were also some global option for customizing
that.

Yes, that is what I proposed in thread "proposal - minibuffer completion
functions". One significant advantage is that all code that calls
`completing-read' while the binding is in effect can then take advantage of the
custom reading behavior.

This change should be accompanied with a new function
ido-completing-read since the initial request was to use
ido style completion in Info-mode.
