The default output is the same as '-1', correct.

However, if you choose to implement the extra credit options '-C' and
'-x', then this changes, and '-C' becomes the default if output goes to
a terminal.  (-1 remains the default for output that does not go to a
terminal.)

P.S.: I noticed that the reference manual page does not actually
document the '-C' and '-x' options.  I've just added those, so please
refresh should you end up working on the extra credit.
