Subject: [PATCH v3 07/23] cat-file: start migrating formatting to ref-filter
Date: Mon, 12 Feb 2018 08:08:54 +0000	[thread overview]
Message-ID: <01020161890f4348-10a54126-e31d-448d-93a3-55fd89c248c4-000000@eu-west-1.amazonses.com> (raw)
In-Reply-To: <01020161890f4236-47989eb4-c19f-4282-9084-9d4f90c2ebeb-000000@eu-west-1.amazonses.com>

Move mark_atom_in_object_info() from cat-file to ref-filter and
start using it in verify_ref_format().
It also means that we start reusing verify_ref_format() in cat-file.

Start from simple moving of mark_atom_in_object_info(),
it would be removed later by integrating all needed processes into
ref-filter logic.
