Re: lexical binding changes symbol standard-value property

(car (get 'dummy-var 'standard-value)) is defined to contain an
*expression* rather than a *value*.

Using `eval' is (and always has been) the only correct way to get the
"standard-value".

E.g.

    (defcustom sm-test (+ 1 2) "hello")
    (car (get 'sm-test 'standard-value))

returns (+ 1 2) rather than 3 (well, with lexical-binding it returns
yet something else, but that is also an expression which evaluates to
3).
