"More concise formatting for dummy implementations" can be less concise #3872
Description
Describe the bug
TLDR: #3796 ("More concise formatting for dummy implementations") can make stuff longer.
To Reproduce
def long_function_with_sine_params_and_long_return(param, another_one) -> ReturnType:
...which is fine in the current style, is now formatted, in the preview style, as
def long_function_with_sine_params_and_long_return(
param, another_one
) -> ReturnType: ...which is longer than before.
Expected behavior
I am not sure:
- Accept this new behavior?
- Allow
...on a line of its own if appending it to the previous line leads to line breaks? - Disregard trailing
...in line-break computations?
Environment
- Black's version: 23.9.0
- OS and Python version: 3.11.5
