Subject: [PATCH v3 2/8] for-each-ref: explicitly test no matches
Date: Wed, 15 Mar 2023 17:45:37 +0000	[thread overview]
Message-ID: <f56d6a64d24147b4fc59118d82029fbe7cd5af38.1678902343.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1489.v3.git.1678902343.gitgitgadget@gmail.com>

From: Derrick Stolee <derrickstolee@github.com>

The for-each-ref builtin can take a list of ref patterns, but if none
match, it still succeeds (but with no output). Add an explicit test that
demonstrates that behavior.
