Suppose we implement a keyword in defcustom that causes it to generate
all that. That will look nice in the source code, but at execution
time it will be equivalent to the above.
I think that would be clearly better than all three of the above
solutions.
Even with my original solution, which simplifies the work somewhat,
scanning the Emacs source tree (_including_ the C source) for
everything that influences the standard value and then rewriting the
equivalent expression (often from C to Lisp) in the defcustom can
take, in certain cases, quite some work.
Doing this work is the only way to get the benefit, so let's do it.
