Subject: [PATCH v4 13/19] rebase: add an --am option
Date: Thu, 16 Jan 2020 06:14:27 +0000
Message-ID: <5478c730acad0423399de018f2099c07fefbb190.1579155273.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.679.v4.git.git.1579155273.gitgitgadget@gmail.com>

From: Elijah Newren <newren@gmail.com>

Currently, this option doesn't do anything except error out if any
options requiring the interactive-backend are also passed.  However,
when we make the default backend configurable later in this series, this
flag will provide a way to override the config setting.
