Subject: [PATCH RFC v2 15/25] ref_filter: add is_atom_used function
Date: Mon, 5 Feb 2018 11:27:39 +0000	[thread overview]
Message-ID: <0102016165b8b459-938aff59-da10-4b83-9e42-cd6feb06adb5-000000@eu-west-1.amazonses.com> (raw)
In-Reply-To: <0102016165b8b3c4-54efe4c4-6d19-435d-b5b9-6c727771353b-000000@eu-west-1.amazonses.com>

Delete all items related to split_on_whitespace from ref-filter
and add new function for handling the logic.
Now cat-file could invoke that function to implementing its logic.
