Subject: bug#17127: `call-process' circumvents password concealment w/ `read-passwd'

To reproduce with emacs -nw -q on 24.3 and trunk:

  M-: (global-set-key
        (kbd "C-c C-c")
        (lambda ()
          (interactive)
          (call-process "echo" nil t nil "-n" "foobar")))

  M-: (read-passwd "Password: ")

  C-c C-c

"foobar" is printed in the minibuffer rather than "......", whereas,
e.g., yanking from the kill ring print dots.
