This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs <at> gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':



Hello,
This piece of code should really be part of emacs defaults !
Best regards, and thanks for emacs.

+1, at least for adding the definition.

FWIW, that's exactly the code I have in misc-cmds.el.

Wrt binding f5 by default:

Emacs Dev generally avoids binding function keys by default, as it should.  But
they have already created default bindings for some function keys (they should
*not* have, IMHO).

Also, function keys are repeatable keys (just hold one down to repeat it), and
as such they should generally be used for repeatable commands.  We should
generally put commands (such as buffer reverting) that are typically not
repeated on other key sequences, and not waste repeatable keys on them.

But this binding could be made by default on MS Windows perhaps.  On that
platform f5 is revert/update/refresh for applications generally.

(Personally/FWIW, I bind it to f5 on all platforms.)

Personally, I don't think it's a good suggestion:

1. A user might stumble on the command accidentally (that's what the
confirmation is for).

2. (define-key global-map [f5] 'revert-buffer-no-confirm)

is not that much shorter than

  (define-key global-map [f5] (lambda () (interactive) (revert-buffer t 
t)))

C-h k <f5>, C-h b and friends won't display much helpful information in
this case.

I don't think that any key should be bound to revert-buffer without
confirmation.  It is too easy to hit the key by accident.

2 : No indeed, it not much longer, but only you knows how to do this 
(and me now!)
