#1693546: don't add quotes around RFC 2231 encoded values.
The RFC is bit hard to understand on this point, but the examples
clearly show that parameter values that are encoded according
to its charset/language rules don't have surrounding quotes, and
the ABNF does not allow for quotes. So when we produce such
encoded values, we no longer add quotes.
