Subject: [RFC 05/11] thread: common sorting code
Date: Sun, 16 Aug 2015 08:37:53 +0000	[thread overview]
Message-ID: <1439714279-21923-6-git-send-email-e@80x24.org> (raw)
In-Reply-To: <1439714279-21923-1-git-send-email-e@80x24.org>

We'll be sharing the same threading, so it makes sense to sort
replies using the same code and message headers without repeating
ourselves.

This also standardizes on sorting on X-PI-TS (Unix epoch in seconds)
instead over using X-PI-Date differently in two different places
