ido-completing-read modifies the choices argument

Hi,

When a default value is passed to ido-completing-read, it removes the
default value from the choices(argument).
I wonder whether this is a bug or desired behaviour.


(defun ido-make-choice-list (default)
  ;; Return the current list of choices.
  ;; If DEFAULT is non-nil, and corresponds to an element of choices,
  ;; it is put to the start of the list.
  (let ((ido-temp-list ido-choice-list))
    (if default
(progn
  (setq ido-temp-list
(delete default ido-temp-list))
  (setq ido-temp-list
(cons default ido-temp-list))))
    ; (run-hooks 'ido-make-choice-list-hook)
    ido-temp-list))

This is probably due to how ido works i.e. it displays the default item
as the first item so that RET give you the default value.

Has this caused you any problem? Sorry for the late reply.
