RE: Getting more info on a variable in Customize buffers

[Drew Adams]

       2. More useful than just seeing the installed value would be
          an action to _reset_ the variable to the installed value.

    Clicking on "State" and choosing "Erase Customization" does
    exactly that.

Great. Then the only value I can see in showing the installed value is to
let you know what you'll get if you Erase Customization. That could be done
by showing the new value and asking for confirmation when you click Erase
Customization.

And, since Erase Customization only applies to the current variable, it
should be called something like Reset Value, or Reset to Installed Value.
The current name can give the impression that it erases all customization.
