    Don't compare arguments that can be nil
    
    copy-region-as-kill can be called passing nil as `beg' and
    `end'. Magit does that, which caused an error when this advice was in
    effect.
    
    * lisp/ses.el (ses--advice-copy-region-as-kill): avoid comparison
      unless `beg' and `end' are non-nil.
