Subject: [PATCH 06/20] cat-file: start migrating to ref-filter
Date: Tue, 9 Jan 2018 13:05:23 +0000	[thread overview]
Message-ID: <01020160db067b66-c22a78cb-5297-426b-9b11-a20a8c27f74e-000000@eu-west-1.amazonses.com> (raw)
In-Reply-To: <01020160db0679c9-799a0bc4-b6d1-43e2-ad3b-80be4e4c55e9-000000@eu-west-1.amazonses.com>

Start moving all formatting stuff from cat-file to ref-filter.
Start from simple moving, it would be integrated into
all ref-filter processes further.
