Git traditionally overwrites untracked symlinks silently. This will generally not cause massive data loss, but it is inconsistent with the behavior for regular files, which are not silently overwritten. With this change, git refuses to overwrite untracked symlinks by default. If the user really wants to overwrite the untracked symlink, he has git-clean and git-checkout -f at his disposal.
