Help On col command

Hello Can Any1 tell me the difference between the col command and the col command with the -f option.
I tried running both of them but i can't see any difference.
Please guide me.

From "man col"

 Although col accepts half-line motions in its input, it normally does
      not emit them on output.  Instead, text that would appear between
      lines is moved to the next lower full-line boundary.  This treatment
      can be suppressed by the -f (fine) option; in this case, the output
      from col may contain forward half-line feeds (ESC-9), but will still
      never contain either kind of reverse line motion.

Cheers
