Yup, now it works.

For reference, I got rid of the duplicated bk::eol also by using the
folloing code:

bk::generate(ostream_iterator<char>(cout),
        "Command line options not recognized:\n" <<
        ("  \"" << ba::string << '"' << bk::eol) % "",
        vsTest);

Not putting an empty char array after the modulus operator would be
invalid C++ and is thus required.

Thanks again,
Best,
Diederick
