When we consider if a path has been totally rewritten, we did not touch changes from symlinks to files or vice versa. But a change that modifies even the type of a blob surely should count as a complete rewrite. While we are at it, modernise diffcore-break to be aware of gitlinks (we do not want to touch them).
