Subject: [PULL v2 03/30] bios-tables-test: default diff command
Date: Wed, 26 Feb 2020 04:01:13 -0500	[thread overview]
Message-ID: <20200226090010.708934-4-mst@redhat.com> (raw)
In-Reply-To: <20200226090010.708934-1-mst@redhat.com>

Most people probably just want diff -u. So let's use that
as the default.
