While we are on minibuffer history subject. I suggest to add the
ability of selecting completion from it by using M-h:

(defun complete-from-minibuffer-history ()
  "Take the history list and make it available as a `completions' buffer"
  (interactive)
       (with-output-to-temp-buffer "*Completions*"
           (display-completion-list (symbol-value minibuffer-history-variable))
           (save-excursion
               (set-buffer standard-output)
               (setq completion-base-size 0))))

(defun keymap-test (var)           ; internal function for keymap checking
       (and (boundp var)
            (keymapp (symbol-value var))))

(let ((minimaps (apropos-internal "mini" 'keymap-test))
      map op)
       (while minimaps
           (setq map (symbol-value (car minimaps)))
           (setq minimaps (cdr minimaps))
           (define-key map "\eh"  'complete-from-minibuffer-history)))

Ehud.
