With v3.12.0 shfmt changed the behavior of the `--simplify` option to
ignore any EditorConfig when it's provided. Therefore, this option is
now moved to the EditorConfig as suggested by the shfmt author. See
https://github.com/mvdan/sh/issues/1173 for details.
This skips recursive parsing of the parents of an entity, as just its
direct parents are required by the implmentation. It also simplifies how
such calls are cached. This leads to much cleaner and faster code.
While the desired options for indent size and style are Python's
defaults, let's make it explicit by specifying it in the EditorConfig.
As part of this, this also removes unnecessary inline formatting options
for Python files.
