Subject: [PATCH v2 24/27] userdiff tests: assert empty hunk header context on -U<large>

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Mon, 15 Feb 2021 16:44:24 +0100

Assert the existing behavior that under -U<large> we'll show no hunk
header context, where <large> takes us past the potential hunk header
we'd have extracted. I'm just picking a number over nine thousand as a
really large number we're unlikely to exceed in these tests.
