Subject: [PATCH v1 2/5] diff-merges: refactor set_diff_merges()
Date: Sat, 10 Apr 2021 20:16:54 +0300	[thread overview]
Message-ID: <20210410171657.20159-3-sorganov@gmail.com> (raw)
In-Reply-To: <20210410171657.20159-1-sorganov@gmail.com>

Split set_diff_merges() into separate parsing and execution functions,
the former to be reused for parsing of configuration values later in
the patch series.
