Feature or enhancement

Proposal:

Add a new parameter to the pprint function that inserts a newline character (\n) after the opening parenthesis, and sets the indent to level * indent. With this parameter, pprint will format nested objects in a manner similar to how formatters like Black or Ruff format them.

>>> t = {'a':2, 'b':{'x':3, 'y':{'t1': 4, 't2':5}}}
>>> pprint(t, indent=4, some_parameter=True)
{
    "a": 2,
    "b": {
        "x": 3,
        "y": {
            "t1": 4,
            "t2": 5
        }
    }
}

With this change, pprint will print in a more width-compact manner, making it easier to read and copy-page pretty printed object to codebase wich follows similar formmating rule.
