Subject: [PATCH 2/8] ahead-behind: parse tip references
Date: Mon, 06 Mar 2023 14:06:32 +0000 [thread overview]
Message-ID: <08fc0710017d4b6178a8c5772e0f15fc69c84ad6.1678111599.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.1489.git.1678111598.gitgitgadget@gmail.com>
From: Derrick Stolee <derrickstolee@github.com>
Before implementing the logic to compute the ahead/behind counts, parse
the unknown options as commits and place them in a string_list.
Be sure to error out when the reference is not found.
