It's unclear to me if Python 3.5 is affected or not.

The fix changes the function _fold_as_ew(), Python 3.5 doesn't have this function *but* there is a call a _fold_as_ew() method!?

Lib/email/_header_value_parser.py:427: in _fold() method

            ...
            if is_ew or last_ew:
                # It's too big to fit on the line, but since we've
                # got encoded words we can use encoded word folding.
                part._fold_as_ew(folded)
                continue
            ...

If I backport the 2 tests, they fail *but* they don't hang forever (they complete in less than 1 second).
