From 729e72ef484fb7853282184608007bad017ae943 Mon Sep 17 00:00:00 2001
From: Miloslav Trmač <mitr@redhat.com>
Date: Wed, 18 Jul 2018 23:27:48 +0200
Subject: Replace optional nameToPull.shaPullName with mandatory dstName
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This consolidates the shaPullName logic into a single place,
(and eliminates the unclear shaPullName member name completely).
The resulting nameToPull will shortly be more generally useful.

Should not change behavior.

Closes: #1112
