title: In python, how to tweak Black formatter, if possible?
body: <p>I know that Black is an opinionated formatter, but I love everything it does except one major thing. When I have a function with multiple arguments, instead of displaying it like this:</p>
  
  <pre><code>def example_function(arg_1: str, arg_2: bool, arg_3: int = 0, arg_4: int = 1, arg_5: float = 0.0):
      pass
  </code></pre>
  
  <p>I'd rather display it as follows for readability</p>
  
  <pre><code>def example_function(
      arg_1: str, 
      arg_2: bool, 
      arg_3: int = 0, 
      arg_4: int = 1, 
      arg_5: float = 0.0
  ):
  </code></pre>
  
  <p>Is this achievable with Black or some other formatter? I have this problem several times and it makes me consider not to use Black, either something else or nothing at all. Any ideas or comments?</p>
