Subject: [PATCH v2 07/13] rebase: add REBASE_DEFAULT
Date: Fri, 18 Dec 2020 15:10:20 -0600 [thread overview]
Message-ID: <20201218211026.1937168-8-felipe.contreras@gmail.com> (raw)
In-Reply-To: <20201218211026.1937168-1-felipe.contreras@gmail.com>
By introducing a default we can distinguish when the user has forced an
option.
Therefore there's no need pass around an extra variable variable (it's
the same as opt_rebase == REBASE_DEFAULT), nor is there any need to
initialize opt_rebase to an invalid value.
Additionally this will allow us to override the default with a
configuration, and subsequently the configuration with arguments.
