bug#16091: 24.3.50; show-paren-mode highlights parentheses in minibuffer password prompts

[Nicolas Semrau]

emacs -q

M-x show-paren-mode

M-x eshell or M-x shell

Enter a command that triggers a dotted password prompt in the
minibuffer, e. g. su or sudo.

When you type a password containing matching or non-matching parentheses
into the prompt: show-paren-mode kicks in and highlights the
character(s) that represent the (non-)matching parentheses.  This makes
the "secret" input a bit less secret.

Expected behaviour: show-paren-mode should not highlight parentheses in
a secret minibuffer string.
