[PATCH] rename 'bandwidth' to 'transfer' in output

[Tomasz Torcz <tomek@pipebreaker.pl>]

  'bandwidth' is a measure of speed, but wg's output shows only
 total number of bytes transferred. Thus 'transfer' is a better label.
  For script-friendly output mode, both 'transfer' and 'bandwidth'
 are accepted (for backward compatibility) but only former is documented.
