bug#27286: 25.2; kill-matching-buffers without confirmation

[R. Diez]

Hi there:

Please add a clean way for 'kill-matching-buffers' to not ask for
confirmation. I need this for non-interactive usage.

The work-around usually proposed involves using 'flet' or some other hack, like
copying and modifying an Emacs internal function (which could change in
the future, thus breaking your copy).

I was advised to create this bug so that it "gets more traction".

I have already discussed this enhancement with the Emacs developers, and
I think that there was consensus that this feature would be useful. More 
detailed
information is in this mailing list thread:
