It's very nice. With your version it is e.g. possible, to print a big
table in a way, so that much information can be seen at the same time,
which makes comparison much easier (faster and more reliable). It seems
to be near to the version of pretty print, I've been looking for.
But: Without putting it on the User Contributions Page, you can't get
Micro $$ for it.

I changed this to 1.

I changed this to pp.

I don't have the time to make extensive tests at the moment. But I
will use your version on a regular basis, instead of the official
pretty_print(), to gather some experience.

Many thanks, and best regards,
