bug#12104: 24.1; customize-variable: Customize buffer does not hide standard settings

[Raffaele Ricciardi]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgement at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

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':

- emacs -Q
- M-x customize-variable RET blink-matching-delay RET

The Customize buffer shows the value of the option, whereas according
to the News it should starts out hidden because the value has not been
changed.

Anyway, I think that hiding the values of options betrays the 
expectations of
users, as no other application I know of does so.  At least, such hiding
should be configurable (I've found no option to change it).  Emacs already
detects and shows in the State field whether a variable has been changed or
not.

Thank you for your attention.

Regards

It means in the customize group buffer. Compare

emacs -Q
M-x customize-group RET paren-blinking RET

in 24.1 and 23.4.
