docs: Get an option value for a given section.
  
          If `vars' is provided, it must be a dictionary. The option is looked up
          in `vars' (if provided), `section', and in `defaults' in that order.
  
          All % interpolations are expanded in the return values, unless the
          optional argument `raw' is true. Values for interpolation keys are
          looked up in the same manner as the option.
  
          The section DEFAULT is special.
