boost::to_string(boost::original_exception_type) needs demangling

[sarum9in@…]

Header: boost/exception/detail/exception_ptr.hpp

Current definition of original_exception_type is

typedef error_info<struct tag_original_exception_type,std::type_info const *> original_exception_type;

It uses std::type_info to store original type.

Current definition of to_string is

    inline
    std::string
    to_string( original_exception_type const & x ) 
        {   
        return x.value()->name();
        }

to_string() returns std::type_info::name() without demangling, so user gets type name like "St13runtime_error". It would be better to get "std::runtime_error".

I suggest using

    inline
    std::string
    to_string( original_exception_type const & x ) 
        {   
        return units::detail::demangle(x.value()->name());
        }   

units::detail::demangle() is already used in boost::exception library, so no new dependency is introduced.
