[3.11] gh-121284: Fix email address header folding with parsed encoded-word (GH-122754) (GH-131405)
Email generators using email.policy.default may convert an RFC 2047
encoded-word to unencoded form during header refolding. In a structured
header, this could allow 'specials' chars outside a quoted-string,
leading to invalid address headers and enabling spoofing. This change
ensures a parsed encoded-word that contains specials is kept as an
encoded-word while the header is refolded.
[Better fix from @bitdancer.]
(cherry picked from commit 295b53df2aa18deb625a7da41f7e4babfe6ef34b)
