Change

"""Test docstring"""
a = 1

to

"""Test docstring"""

a = 1

in preview style, but don't touch the docstring otherwise.

Do we want to ask black to also format the content of module level docstrings? Seems inconsistent to me that we change function and class docstring indentation/contents but not module docstrings.

Fixes #7995

Trying to understand, why / how is this happening?

Ah, I see, there's a bug in try_from_docstring that's fixed in that PR. I'm just gonna copy that fix in here -- seems odd to commit without it.

my plan was to merge the other one first and then rebase, but this does too

I don't think bytes can be used as docstrings, right?

$ cat src/play.py                                           
b"docstring"

Thanks for making double check! psf/black#4002

We previously incorrectly treated byte strings in docstring position as docstrings because black does so (#8283 (comment), psf/black#4002), even CPython doesn't recognize them:

```console
$ python3.12
Python 3.12.0 (main, Oct  6 2023, 17:57:44) [GCC 11.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> def f():
...     b""" a"""
...
>>> print(str(f.__doc__))
None
```

This conflicts with https://github.com/asottile/reorder-python-imports v3.12.0 which removes any blank lines between the module docstring and the import lines.

i.e. ruff format in v0.3.0 has the same issue reported in black as psf/black#4175 which is currently unresolved.

P.S. See also asottile/reorder-python-imports#366 - we can expect no fixes there 😞

Update: Consensus seems to be switch to isort instead.
