Don't squeeze hanging comments to the left

[grantjenks]

Let's consider not squeezing hanging comments to the left, e.g. not doing this:

-    def _coerce(self, value, default: Optional[int] = 0) -> Optional[int]:      # type: ignore[no-untyped-def]
+    def _coerce(self, value, default: Optional[int] = 0) -> Optional[int]:  # type: ignore[no-untyped-def]

And here's an egregious example from flufl.i18n:

-    aqua = 'aardvarks'                          # noqa: F841
-    blue = 'badgers'                            # noqa: F841
-    cyan = 'cats'                               # noqa: F841
+    aqua = 'aardvarks'  # noqa: F841
+    blue = 'badgers'  # noqa: F841
+    cyan = 'cats'  # noqa: F841

The latter is definitely less readable.

Here's what black does for long arg lists:

def test(arg1001, arg1002, arg1003, arg1004, arg1005, arg1006, arg1007, arg1008, arg1009, arg1010):     # noqa
    pass

to

def test(
    arg1001,
    arg1002,
    arg1003,
    arg1004,
    arg1005,
    arg1006,
    arg1007,
    arg1008,
    arg1009,
    arg1010,
):  # noqa
    pass

It would be nice to preserve the column of the original comment.

+1'ing again after formatting grantjenks/python-diskcache. Hanging comments are necessary and the jagged pattern hurts my eyes.
