#3851 from alexrudy/pretty-newlines
Adds an explicit newline for pretty-printing.
Included:
- ``p.break_()`` inserts a hard newline in the output, maintaining the correct indentation during pretty printing.
- When the pretty printer falls back to the object's ``__repr__`` method, newlines are converted from ``\n`` to ``p.break_()`` to maintain indentation
