    Glib::ustring: Delete an obsolete TODO comment
    
    * glib/glibmm/ustring.cc: The comment added 2007-08-12 by commit
    https://git.gnome.org/browse/glibmm/commit/?id=132b0ceb8c30ef82a6c11635eff8e7b41feba357
    is obsolete or a misunderstanding. A std::wostream requires a wchar_t string
    as input from the C++ code, but the character encoding of a written file is
    determined by the std::wostream's std::locale.
