Subject: [PATCH] view: conditionally anchor to thread skeleton
Date: Sun, 10 Jul 2016 01:24:08 +0000
Message-Id: <20160710012408.31380-1-e@80x24.org>
List-Id: <meta@public-inbox.org>

We only care about the thread skeleton if we have
multiple messages in a thread, single message threads
can just go to the top of the message.
