Program Options has issues with options that support multiple tokens when using multiple parsers

[Devin Crumb <dcrumb@…>]

If you have an option that allows multiple tokens and give that option at both command line and config file, only the tokens listed on the command line are saved.

I fixed this issue by changing:

            // If option has final value, skip this assignment
            if (xm.m_final.count(name))
                continue;

            const option_description& d = desc.find(name, false, 
                                                      false, false);

to:

            const option_description& d = desc.find(name, false, 
                                                      false, false);

            // If option has final value, skip this assignment
            if ((xm.m_final.count(name)) && (d.semantic()->max_tokens() <= 1))
                continue;
