It's not possible, as I never saw a config file with positional options.

The 'include_positional' you mention is defined like this:

    /** Controls if the 'collect_unregistered' function should
        include positional options, or not. */
    enum collect_unrecognized_mode 
    { include_positional, exclude_positional };

so it only applies to collect_unregistered function. As config file
parser will never return positional options, 'include_positional' is
of no use.

Does this clarifies things?
