Subject: [PATCH v2 05/11] builtin rebase: support the `verbose` and `diffstat` options
Date: Tue, 04 Sep 2018 14:27:13 -0700 (PDT)	[thread overview]
Message-ID: <ce1e1f266a8ec6c31576dfe871b1482015159af0.1536096424.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.32.v2.git.gitgitgadget@gmail.com>

From: Pratik Karki <predatoramigo@gmail.com>

This commit introduces support for the `-v` and `--stat` options of
rebase.

The --stat option can also be configured via the Git config setting
rebase.stat. To support this, we also add a custom rebase_config()
function in this commit that will be used instead of (and falls back to
calling) git_default_config().
