bug#20142: 25.0.50; confirm-kill-emacs called again after failing once

[Michael Heerdegen]

Hello,

this seems to be a recent regression:

in emacs -Q, M-: (setq confirm-kill-emacs #'yes-or-no-p).

Then I click on the "close" button of the (only) frame.  I get a popup
prompting "Really exit Emacs" as expected.  I click on "No".  After
that, a popup with the same content appears again.  After saying "No"
the second time, it stops asking.

That doesn't happen with C-x C-c btw, only when "using the mouse".


Thanks in advance,

Michael.
