#10448: MSVC bug with default argument passing - a workaround is required

 MSVC 2010-2013 for x64 may pass default values incorrectly.

 I met this bug with such innocent code:
 {{{
 std::wcout << boost::filesystem::path(L"ABC");
 }}}
 and got hieroglyphs around ABC instead of quotation marks.

 To workaround the bug: just add '''(Char)''' prior to default values in
 the declaration of boost::io::detail::quote
 (boost/io/detail/quoted_manip.hpp)

 {{{
     //  manipulator for const std::basic_string&
     template <class Char, class Traits, class Alloc>
       detail::quoted_proxy<std::basic_string<Char, Traits, Alloc> const &,
 Char>
         quoted(const std::basic_string<Char, Traits, Alloc>& s,
                Char escape=(Char)'\\', Char delim=(Char)'\"');

     //  manipulator for non-const std::basic_string&
     template <class Char, class Traits, class Alloc>
       detail::quoted_proxy<std::basic_string<Char, Traits, Alloc> &, Char>
         quoted(std::basic_string<Char, Traits, Alloc>& s,
                Char escape=(Char)'\\', Char delim=(Char)'\"');

     //  manipulator for const C-string*
     template <class Char>
       detail::quoted_proxy<const Char*, Char>
         quoted(const Char* s, Char escape=(Char)'\\', Char
 delim=(Char)'\"');

 }}}
 I did not scan other sources with similar problem; could you please check
 them yourselves?
