If I remember (and understood) correctly, Richard rejected this kind
of solution when we first discussed this problem.

It gives at least two problems I am aware of:

1.  Loading tooltip again will set the standard value to nil again.

2. Selecting "Show initial Lisp expression" in a Custom buffer will
   not show the correct expression.  This expression is useful if you
   want to customize variables whose default depends on a bunch of
   stuff, because looking at that expression will ensure that you are
   aware of all aspects of the problem.

There may very well be other problems.  Custom just assumes that the
standard value is the expression given in the defcustom.

It certainly would simplify things if we could simply set the standard
values of all 20+ remaining options in the `emacs -q M-x customize-rogue'
buffer to the actual values they have just before the init files are
read in startup.el, as Lennart Borgman proposed (if I remember
correctly).  But Richard rejected that and, as pointed out above,
there are some problems with that approach.

Sincerely,

Luc.
