Fingers of some "git diff" users are trained to do --name-only which git-ls-tree unfortunately does not take. With this, cd sub/directory && git-ls-tree -r --name-only .. would show only the names not object names nor modes. I threw in another synonym --name-status only for usability, but obviously ls-tree does not do any comparison so what it does is the same as --name-only.
