Subject: [PATCH 1/2] thread: reduce indentation level
Date: Thu, 13 Oct 2016 03:59:02 +0000
Message-ID: <20161013035903.1726-2-e@80x24.org> (raw)
In-Reply-To: <20161013035903.1726-1-e@80x24.org>

This should reduce differences from the original Mail::Thread
code and hopefully make things easier-to-follow.
