+\r
+If we start with the obvious:\r
+\r
+ notmuch show --output-headers=date,from,subject,to,cc,reply-to ...\r
+\r
+with the default being the current set.\r
+\r
+Emitting everything would be easier but seems wasteful. I just looked\r
+at a random message: in RFC822 syntax the header is 4073 bytes, and the\r
+body is 1116 bytes. Keeping only the fields that notmuch emits reduces\r
+the header to 295 bytes. Reply-To is 92 bytes, but not every message\r
+has that.\r
