Subject: [PATCH 16/20] merge-ort: basic outline for merge_switch_to_result()
Date: Thu, 29 Oct 2020 20:41:27 -0700	[thread overview]
Message-ID: <20201030034131.1479968-17-newren@gmail.com> (raw)
In-Reply-To: <20201030034131.1479968-1-newren@gmail.com>

This adds a basic implementation for merge_switch_to_result(), though
just in terms of a few new empty functions that will be defined in
subsequent commits.
