Subject: [PATCH 10/16] net_reader: fix single NNTP article fetch, test ranges
Date: Sun, 19 Sep 2021 12:50:29 +0000 [thread overview]
Message-ID: <20210919125035.6331-11-e@80x24.org> (raw)
In-Reply-To: <20210919125035.6331-1-e@80x24.org>
While NNTP ranges was already working, fetching a single message
was broken. We'll also simplify the code a bit and ensure
incremental synchronization is ignored when ranges are
specified.
