+Subject: [PATCH] 00435: gh-121650: Encode newlines in headers, and verify
+ headers are sound (GH-122233)
+
+Per RFC 2047:
+
+> [...] these encoding schemes allow the
+> encoding of arbitrary octet values, mail readers that implement this
+> decoding should also ensure that display of the decoded data on the
+> recipient's terminal will not cause unwanted side-effects
+
+It seems that the "quoted-word" scheme is a valid way to include
+a newline character in a header value, just like we already allow
+undecodable bytes or control characters.
+They do need to be properly quoted when serialized to text, though.
+
+This should fail for custom fold() implementations that aren't careful
+about newlines.
+
