Thanks ludo!
With your helo, I can easily hack the colorized REPL now!
But I realized that the hook maybe an improper way to go, it'll print
twice:
-----------------example---------------
123 (colorized output)
$1 = 123 (normal output)
-------------------end-----------------

And I checked the code, it'll call 'pp' after 'before-print-hook', so
the add the colorized code into 'pp' will be more pretty.

I think a colorized REPL is useful for our users.
Will you accept a patch to 'pp' for colorized REPL? Or an easy way, a
module with hook to do the same job, but output twice?
