commit 96281c5ee1582ac0c329d09797ab7ab3dbae26d1

    Record :version for built-in variables while dumping
    
    * lisp/cus-start.el (standard): Record the ':version; of the
    symbols when dumping, so that 'describe-variable' could tell
    which built-in variables were added/changed in recent
    versions.
