Subject: [RFC PATCH 04/13] walken: add handler to git_config
Date: Thu,  6 Jun 2019 18:08:02 -0700	[thread overview]
Message-ID: <20190607010811.52944-5-emilyshaffer@google.com> (raw)
In-Reply-To: <20190607010811.52944-1-emilyshaffer@google.com>

For now, we have no configuration options we want to set up for
ourselves, but in the future we may need to. At the very least, we
should invoke git_default_config() for each config option; we will do so
inside of a skeleton config callback so that we know where to add
configuration handling later on when we need it.
