Subject: [PATCH v4 05/24] merge-recursive: introduce an enum for detect_directory_renames values
Date: Sat, 17 Aug 2019 11:41:25 -0700	[thread overview]
Message-ID: <20190817184144.32179-6-newren@gmail.com> (raw)
In-Reply-To: <20190817184144.32179-1-newren@gmail.com>

From: Derrick Stolee <dstolee@microsoft.com>

Improve code readability by introducing an enum to replace the
not-quite-boolean values taken on by detect_directory_renames.
