I'm having second thoughts about this test. I'm not sure notmuch can do better than treat all of the things that look like message-ids in In-reply-to as references. RFC 5322 (which I called 5822 above) talks about obsolete syntax, and in particular 4.5.4 discusses obsolete In-Reply-To and References syntax. I _think_ (but am not 100% sure), that even under that generous syntax, just grabbing the things that look like message-ids is the best thing to do. d
