Adding from-stdin = false to toml config causes pylint to hang

[BrianHVB]

Overview

At the end of the docs on configuration (main section - https://pylint.readthedocs.io/en/latest/user_guide/configuration/all-options.html#main-checker), there is an example configuration section with the following code:

[tool.pylint.main]
analyse-fallback-blocks = false

clear-cache-post-run = false

# ...

from-stdin = false

ignore = ["CVS"]

# ...

If you use this configuration inside of a .toml file, then run pylint on a file, the process will hang indefinitely, with no output. The issue was traced back to the from-stdin setting.

Steps to reproduce

1. Create a Python project/directory
2. Create a pyproject.toml file with the following content:

[tool.pylint.main]
from-stdin = false

3. Create a python file (test.py) with some basic Python code
4. From the project root, run pylint ./test.py
5. Note that Pylint hangs
6. Comment out or remove the from-stdin = false line.
7. Rerun pylint ./test.py
8. Notice that it runs successfully
