bug#11978: 23.2; F5 and revert without confirmation

[Romain TROIT]

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@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.
William
