Use the whole width of the terminal assume width of 80 if none found Show percentages in the final column. Show ASCII bars indicating usage of the underlying directories in the space inbetween. Display (height of terminal - 10) entries by default. Reverse the output order so largest is at the bottom. Break up tests. Change older tests to check real output of program.
