Subject: [PATCH v4 21/34] merge-recursive: make a helper function for cleanup for handle_renames
Date: Tue, 28 Nov 2017 17:42:24 -0800	[thread overview]
Message-ID: <20171129014237.32570-22-newren@gmail.com> (raw)
In-Reply-To: <20171129014237.32570-1-newren@gmail.com>

In anticipation of more involved cleanup to come, make a helper function
for doing the cleanup at the end of handle_renames.  Rename the already
existing cleanup_rename[s]() to final_cleanup_rename[s](), name the new
helper initial_cleanup_rename(), and leave the big comment in the code
about why we can't do all the cleanup at once.
