Currently: >>> pprint.pprint({"a": "xxx " * 50}) {'a': 'xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx '} It would be nicer if it produced something like: >>> pprint.pprint({"a": "xxx " * 50}) {'a': 'xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx ' 'xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx ' 'xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx ' 'xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx ' 'xxx xxx xxx xxx xxx xxx xxx xxx xxx xxx '} (for the record, the real-world use case I encountered was when printing some pyudev data)

I like this. It would be especially nice if it were smart enough to split the segments after sequences of line-ends (r'(\r?\n)+').

I was thinking we could re-use textwrap, actually.
