Subject: [PATCH v4 15/34] merge-recursive: move the get_renames() function
Date: Tue, 28 Nov 2017 17:42:18 -0800 [thread overview]
Message-ID: <20171129014237.32570-16-newren@gmail.com> (raw)
In-Reply-To: <20171129014237.32570-1-newren@gmail.com>
I want to re-use some other functions in the file without moving those
other functions or dealing with a handful of annoying split function
declarations and definitions.
