Incorrect comment in test/karma/real.hpp

[Mateusz Loskot]

In the aformentioned file, there is this type defined:

template <typename T>
struct fixed_policy : boost::spirit::karma::real_policies<T>
{
    typedef boost::spirit::karma::real_policies<T> base_type;

    //  we want the numbers always to be in scientific format
    static int floatfield(T) { return base_type::fmtflags::fixed; }
};

The last comment should likely end with: in fixed notation format

This is about cosmetics, but as the comments serve purpose of documenting, it may be worth to correct it.
