kill-matching-buffers without confirmation

[R. Diez]

Hallo all:

Could someone please add a clean way for 'kill-matching-buffers' to not ask for 
confirmation? Apparently, I am not the only once that has hit this nag:

https://stackoverflow.com/questions/10929915/how-do-i-answer-y-automatically-kill-matching-buffers-asks-if-i-should-kill-a-m

I am tired of overriding 'kill-buffer-ask' with flet as suggested there, and 
then seeing this warning:

Warning (bytecomp): ‘flet’ is an obsolete macro (as of 24.3); use either 
‘cl-flet’ or ‘cl-letf’.

And then remembering that cl-flet does not work, and it gets complicated with 
Lisp macros, dynamic something, etc. I am no Elisp expert.


I am sending this e-mail to this mailing list because that function lives in 
files.el, which states at the top:

;; Maintainer: address@hidden
;; Package: emacs


Please copy me on the answer, as I am not subscribed to the list.

Regards,
