+As Daniel Kahn Gillmor <dkg@fifthhorseman.net> reports in\r
+id:87d1ngv95p.fsf@alice.fifthhorseman.net, notmuch show combines\r
+multiple Cc: fields into one, while notmuch reply does not. While such\r
+messages are in violation of RFC 5322, it would be reasonable to\r
+expect notmuch to be consistent. Add a known broken test to document\r
+this expectation.\r
+\r
+Details:\r
+\r
+The original message is formatted using the message printing in\r
+notmuch-show.c. For Cc:, it uses g_mime_message_get_recipients(),\r
+which apparently combines all Cc: fields into one internally.\r
+\r
+The addresses in the reply headers, OTOH, are based on headers queried\r
+through libnotmuch. It boils down to g_mime_object_get_header() in\r
+lib/message-file.c, which returns only the first occurence of header.\r
