      IMO the string should start at lineno=1, col_offset=0.

>>> import ast
>>> a = ast.parse('''"""xxx

>>> ast.dump(a, include_attributes=True)
"Module(body=[Expr(value=Str(s='xxx\\nyyy\\nzzz', lineno=3, col_offset=-1), lineno=3, col_offset=-1)])"

      Victor, I'm adding you just in case this also affects your
      optimizer (like bpo-25555).
