+\r
+By default the reference header is hidden. It is controlled by\r
+message-hidden-headers which you can customize. (Note notmuch adds\r
+user-agent to this list via notmuch-mua-hidden-header.)\r
+\r

+\r
+That isn't my reading of RFC2822 (section 3.6.4):\r
+\r
+ The "References:" field will contain the contents of the parent's\r
+ "References:" field (if any) followed by the contents of the parent's\r
+ "Message-ID:" field (if any).\r
+\r

+\r
+That would be possible. If you don't actually want to include the\r
+message itself then "c f" to stash the from, and then pasting that as\r
+the "to" address gets pretty close.\r
+\r
+Best wishes\r
