3714,"file_system::path::assign clears and appends, precluding assignment to a leading substring of self",joe.pendergast@…,Beman Dawes,"template <class InputIterator>
basic_path & assign( InputIterator first, InputIterator last )
      { m_path.clear(); append( first, last ); return *this; }

this implementation precludes assigning to a path a leading substring of that path itself because most impl's string_type::clear will end up setting the first char to 0. I could not find documentation that explicitly precludes this.

As stated most impl's will end up setting the first char to 0, so this seems to fix in those implementations:

{
   typename string_type::value_type c;
   if(first!=last)c = *first;
   m_path.clear(); 
   append( first, last );
   if(first!=last) mPath[0] = c; 
   return *this; 
}
