Presently, the code which finds the parent of a message as it is being added to the database assumes that the first Message-ID-like substring of the In-Reply-To header is the parent Message ID. Some mail clients, however, put stuff other than the Message-ID of the parent in the In-Reply-To header, such as the email address of the sender of the parent. This can fool notmuch. The updated algorithm prefers the last Message ID in the References header. The References header lists messages oldest-first, so the last Message ID is the parent (RFC2822, p. 24). The References header is also less likely to be in a non-standard syntax (http://cr.yp.to/immhf/thread.html, http://www.jwz.org/doc/threading.html). In case the References header is not to be found, fall back to the old behavior. V2 of this patch, incorporating feedback from Jani and (indirectly) Austin.
