When symlinks in the working tree are manipulated using the absolute path, git dereferences them, and tries to manipulate the link target instead. This applies to most high-level commands but prefix_path is the common denominator for all of them. Add a known-breakage tests using the prefix_path function, which currently uses real_path, causing the dereference.
