From ea1954af771253660cd84dc73b8f2832327c9c02 Mon Sep 17 00:00:00 2001 From: Erwin Villejo Date: Wed, 17 Nov 2021 07:55:50 +0000 Subject: pull: should be noop when already-up-to-date The already-up-to-date pull bug was fixed for --ff-only but it did not include the case where --ff or --ff-only are not specified. This updates the --ff-only fix to include the case where --ff or --ff-only are not specified in command line flags or config.
