bug#15501: 24.3; usage of read-passwd within format-alist

[mhoram]

Hello,

read-password does not hide password characters when used within
format-alist during loading of a file.
Version of Emacs is 24.3.

One can reproduce the bug with "emacs -Q" by loading the following
file
--- BEGIN test.el ---
;ttxxtt

(setq format-alist
      (cons (list 'txtins
                  "txtins"
                  "^;ttxxtt"
                  (lambda (x y) "ins"
                    (goto-char (point-min))
                    (insert ";;" (read-passwd "password: ") "\n")
                    (point-max))
                  nil
                  t
                  nil)
            format-alist))
--- END test.el ---

and executing the setq-statement.  When this buffer is killed and loaded
again, one is asked for the password and the password-characters are
shown in plaintext on display.

I would expect that read-passwd always hides the characters.

Emacs Version 23.3 did not contain this bug.

Best wishes
Markus
