svn commit: r335850 - head/usr.bin/top

Author: eadler

Log:
  top(1): permit infinite length for command
  
  There isn't any need to limit the size of the screen. Utilities like
  'less -S' don't have a (meaningful) limit anyways.  This also makes the
  way to dynamically changing the column widths based on the screen width.
