RE: Customize buttons that change user's custom file shouldaskforconfirmation

       ... Another possibility to consider for this might be "Installed
       Values" (or "Stock Values").

    "Stock Values" is best.  It will cause me to ask, `what is meant by
    "stock values" ... ?'

    Like anyone who is not a novice Emacs person, I follow the convention
    and set values in my .emacs file.  Only for features that I do not
    understand, like fonts, do I use customize.  And, of course when I
    realize I made a mistake and can see a better face, I change the
    customized values that I have set within my .emacs file by
    `custom-set-faces'.

    Asking what is meant by "stock values" is worthwhile for people who
    have used Emacs for two decades or more -- for example, off hand, I
    cannot remember whether `customize' considers stock values to be those
    you see with `emacs -Q' or whether it uses the previously set values.
    And the phrase is harmless to novices.

IIUC, the "standard" (stock, or whatever) values are those defined by
defcustom and defface; that's all - the values according to "the spec" (Spec
Values? Defined Values?).

This term does not determine a particular set of options; it refers only to
a particular kind of value for an option - any option. Emacs -Q just uses a
minimal set of libraries and features, so a minimal set of options. Standard
values apply to defcustoms and deffaces from all libraries.
