[lightweight_test] cpp_main convention

Hi,

I noticed this as popular convention across Boost libraries (e.g. endian)
to deal with test cases  that may throw or leak exceptions:

int cpp_main( int argc, char* argv[] )
{
    test();
    return ::boost::report_errors();
}

int main( int argc, char* argv[] )
{
    try
    {
        return cpp_main( argc, argv );
    }
    catch( std::exception const & x )
    {
        BOOST_ERROR( x.what() );
        return boost::report_errors();
    }
}

Is there any reason to prefer that one over this one?

int main( int argc, char* argv[] )
{
    try
    {
        test();
    }
    catch( std::exception const & x )
    {
        BOOST_ERROR( x.what() );
    }
    return boost::report_errors();
}
