Subject: [PATCH 24/48] merge-recursive: Save D/F conflict filenames instead of unlinking them
Date: Wed, 8 Jun 2011 01:30:54 -0600 [thread overview]
Message-ID: <1307518278-23814-25-git-send-email-newren@gmail.com> (raw)
In-Reply-To: <1307518278-23814-1-git-send-email-newren@gmail.com>
Rename make_room_for_directories_of_df_conflicts() to
record_df_conflict_files() to reflect the change in functionality.
