Why not just use what I posted?  There-for you will not have a
trailing eol, if you want a trailing eol then you should just loop it,
not list it, do this:
bk::generate(ostream_iterator<char>(cout),
       "Command line options not recognized:\n" <<
       +("  \"" << ba::string << '"' << bk::eol),
       vsTest);

The + in front of that loop section means 1 or more, you can also use
* for zero or more, but since you should be testing you array size
before you call this anyway, you know you have at least one, you can
also not do an array size test outside of it and do it inside the
parsing function but there is not much point here it is so simple.  :)
