Exactly.  But I'm still in doubt that it is worth adding an optional
KEY argument to `read-passwd'.  It will indeed reduces the code from:

(let ((password (or (password-read-from-cache key)
                    (read-passwd "Password: " confirm default))))
  ... use PASSWORD, and/or check its validity ...
  (if password-should-be-cached
      (password-cache-add key password)))

to:

(let ((password (read-passwd "Password: " confirm default key)))
  ... use PASSWORD, and/or check its validity ...
  (if password-should-be-cached
      (password-cache-add key password)))

This will help programmers only a little, and speaking of this kind of
"risky" code, we should rather require programmers to type more
letters than ordinary code, I think.
