Forcing Colored Output

[Ovid]

Pursuant to comments here:

  http://www.perlmonks.org/?node_id=667414

Since '--color' is the default, people never specify it.  It might be
nice if specifying that *forced* color and we don't try to check if the
output is a TTY.  That way, someone can pipe to 'less -r' and still get
the nicely colored output.

'ack' already allows this (though it still reformats output when piped
to less).

Cheers,
Ovid
