      patches/pylint: fix regression with namedtuples · 5027502c
      Jérome Perrin authored
      with namedtuples and unicode literals enabled, our patch break with:
      
          Module py2stdlib, line 266, in infer_named_tuple
            ''' % {'name': name, 'fields': attributes})
          Module Products.ERP5Type.patches.pylint, line 74, in string_build
            encoding = _guess_encoding(data)
          Module astroid.builder, line 65, in _guess_encoding
            if string.startswith('\xef\xbb\xbf'):
          UnicodeDecodeError: 'ascii' codec can't decode byte 0xef in position 0: ordinal not in range(128)
      
      because pylint/astroid uses string_build to evaluate the named tuple and the source code enabled 
      unicode_literals future, string_build is called with an unicode object.
