If arg is nil, return nil. Error if arg is not nil and not a cons cell. See also `car-safe'. Violates the convention stated in `(elisp)Documentation Tips' that the first line of a docstring should not be wider than 67 characters. (71 in this case.) The only list that is not a cons cell is nil, which is mentioned on the same line. Sincerely, Luc.
