3689	iostreams: multichar_dual_use_filter_tag definition wrong	dk.boost@…	Jonathan Turkanis	"In boost/iostreams/categories.hpp, this definition:

{{{
struct multichar_dual_use_filter_tag 
    : filter_tag, 
      dual_use
    { };
}}}

is wrong, because multichar_dual_use_filter_tag should inherit from multichar_tag.  It should be

{{{
struct multichar_dual_use_filter_tag 
    : multichar_tag, 
      dual_use_filter_tag
    { };
}}}
