Subject: [PATCH v3 04/14] checkout: make "opts" in cmd_checkout() a pointer
Date: Thu, 29 Nov 2018 22:58:39 +0100
Message-ID: <20181129215850.7278-5-pclouds@gmail.com> (raw)
In-Reply-To: <20181129215850.7278-1-pclouds@gmail.com>

"opts" will soon be moved out of cmd_checkout(). To keep changes in
that patch smaller, convert "opts" to a pointer and keep the real
thing behind "real_opts".
