Just increasing the widths doesn't really help that much, because all
the columns may be arbitrarily wide.  A better fix would be to first
compute the max width of all elements, and then use that when
reformatting.

Example:

  /home/larsi/:
  find . \( -maxdepth 1 \) -ls
  find: warning: you have specified the -maxdepth option after a non-option argument (, but options are not positional (-maxdepth affects tests specified before it as well as those specified after it).  Please specify options before other arguments.
