How does Google deal with code refactoring? If one splits the code file into two files, how does the algorithms deals with its former repository commits scoring? Sure splitting classes in Java is hard (one file per class), but in languages like C++, C#, PHP with namespaces it's trivial and happens all the time. (disclaimer: I read ~80% of the article and comments, and used the browser search function, but found no answer)
