+Subject: [PATCH] Use EightBit encoding instead of Base64 for text types
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Previously attachments with text/* or message/rfc822 encoding were
+base64 encoded for no good reason. Change them to use EightBit transfer
+encoding.
