This means that if your history contains something like "rm -rf /",
and you accidently type `M-! M-p RET', your data are lost ;-)
That's why I suggest putting the following code in .emacs:

;; Remove potentially dangerous commands from the history immediately
(add-hook 'minibuffer-exit-hook
          (lambda ()
            (when (string-match
                   "^rm"
                   (car (symbol-value minibuffer-history-variable)))
              (set minibuffer-history-variable
                   (cdr (symbol-value minibuffer-history-variable))))))
