Regression on `master`: Extra newlines added

[adamtheturtle]

Create example.py:

"""My docstring."""

On master docformatter adds newlines here.

I narrowed this down to commit e239dca.
The example below shows that with 1b3f03d there are no changes to the file, but with e239dca, docformatter adds a newline.
I chose Python 3.11 but this applies to other Python versions.

I think I got my investigation a bit mixed up.
