[boost] Re: Documentation error for program_options::positional_options_description::add

Hi Lars,

In boost/boost/libs/program_options/doc/overview.xml revision 1.14, examples state that function program_options::positional_options_description::add accepts three parameters, but the function in boost/boost/boost/program_options/positional_options.hpp revision 1.3 only accepts two parameters.

You're right. I've checked in the fix. Thanks, Volodya
