Subject: [PATCH v4 5/7] reflog tests: test for the "points nowhere" warning

From: Ævar Arnfjörð Bjarmason <[email-masked]>
Date: Thu, 28 Mar 2019 17:14:32 +0100

The "git reflog expire" command when given an unknown reference has
since 4264dc15e1 ("git reflog expire", 2006-12-19) when this command
was implemented emit an error, but this has never been tested for.

Let's test for it, also under gc.reflogExpire{Unreachable,}=never in
case a future change is tempted to take shortcuts in the presence of
such config.
