I think this works as documented: -- Evaluate the top-level form containing point, or after point. If the current defun is actually a call to =E2=80=98defvar=E2=80=99 or =E2= =80=98defcustom=E2=80=99, evaluating it this way resets the variable using its initial value expression (using the defcustom=E2=80=99s :set function if there is one), e= ven if the variable already has some other value. (Normally =E2=80=98defvar=E2= =80=99 and =E2=80=98defcustom=E2=80=99 do not alter the value if there already is one.) -- So only if the def* is top-level does the magic DWIM value-setting thing happen.
