Subject: [PATCH 2/8] commit-graph tests: test a graph that's too small

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Thu, 21 Feb 2019 23:37:47 +0100

Use the recently split-up components of the corrupt_graph_and_verify()
function to assert that we error on graphs that are too small. The
error was added in 2a2e32bdc5 ("commit-graph: implement git
commit-graph read", 2018-04-10), but there was no test for it.
