    users-guide: Disable syntax highlighting
    
    Summary:
    I disabled syntax highlighting for NumericUnderscores extension.
    
    Because pygments does not yet correspond to syntax rule for NumericUnderscores.
    (Sphinx uses pygments as the syntax highlighting.)
    
    I've sent a pull-request to pygments project[1].
    But development of pygments has been suspended since 2017 March.
