Subject: [PATCH 4/6] commit-graph: add --version=<n> option
Date: Wed, 23 Jan 2019 13:59:18 -0800 (PST)
Message-ID: <e7ae3007f55efcccd8827ce7d8db5f9dc180cb39.1548280753.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.112.git.gitgitgadget@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

Allo the commit-graph builtin to specify the file format version
using the '--version=<n>' option. Specify the version exactly in
the verification tests as using a different version would change
the offsets used in those tests.

Signed-off-by: Derrick Stolee <dstolee@microsoft.com>
