bug#25986: 25.2; Disruptive error message in minibuffer with tramp password prompt

[Teemu Likonen]

Emacs gives disruptive error message in minibuffer with tramp password
prompt when show-paren-mode and ido-mode are active. The error message
is:

    Making show-paren-mode local to  *Minibuf-2* while let-bound!

To reproduce:

    emacs -Q -f show-paren-mode -f ido-mode

    C-x C-f /sudo::/e

And the error message is showing and can also be found from the
*Messages* buffer.
