Hi boost,

At version 1.49.0

In testing command line with known unknowns such as -V a location 
unknown exception is thrown from inside program_options recommending to 
use BOOST_THROW_EXCEPTION.  I've been trying to find this and apply 
BOOST_THROW_EXCEPTION to eliminate the verbosity for users:
----
Command line incorrect: Throw location unknown (consider using 
BOOST_THROW_EXCEPTION)
Dynamic exception type: 
boost::exception_detail::clone_impl<boost::exception_detail::error_info_injector<boost::program_options::unknown_option> 
 >
std::exception::what: unknown option -V
----
With this fixed then it'd be closer to:
--------
Command line incorrect: unknown option -V
--------
Yet I haven't found where.  Baffled. Any hint?
