commit ef748b39e022ce98d5aa8110d713368cf39f0ebf
Author: Akira TAGOH <akira@xxxxxxxxx>
Date:   Tue Jan 23 22:27:17 2018 +0900

    Take effects on dir, cachedir, acceptfont, and rejectfont only when loading
    
    Those elements takes effects immediately during parsing config files so makes them conditional to ignore on scanning.
