Subject: [PATCH 07/22] view: simplify duplicate Message-ID handling
Date: Sat, 25 Jan 2020 04:44:55 +0000 [thread overview]
Message-ID: <20200125044510.13769-8-e@yhbt.net> (raw)
In-Reply-To: <20200125044510.13769-1-e@yhbt.net>
It's an uncommon code path, no need to make it more complex
than it needs to be by having extra sub parameters.
