> Not sure how the article's algorithm deals with renames It's relying on `git blame`'s default behavior which is: "The origin of lines is automatically followed across whole-file renames (currently there is no option to turn the rename-following off). To follow lines moved from one file to another, or to follow lines that were copied and pasted from another file, etc., see the -C and -M options."
