[unknown-option-value] False negative after --disable=all

[buhtz]

Bug description

The option --enable does not give an error when an unknown error code is used. It should give an error.

What I was trying is to enable just a group of warnings. I tried W1 and W1*. No error but also no warning. But the code does have some W1203 problems in it.

Configuration

No response

Command used

pylint --disable=all --enable=foobar bandas.py

As I also ran into this issue I started debugging it to check for a fix.

The reason seems to be that --disable=all also disables the unknown-option-value messages.
Thus when running

pylint --disable=all --enable=unknown-option-value,missnig-docstring pylint/checkers/utils.py
************* Module Command line
Command line:1:0: W0012: Unknown option value for '--enable', expected a valid pylint message and got 'missnig-docstring' (unknown-option-value)

------------------------------------
Your code has been rated at 10.00/10

the results is again as expected.

While I understand this behavior for --disable=all, I think it is not very intuitive from a user perspective. I did not expect to silent pylint error messages, most people would assume it only silents linting errors.

Would it make sense to have internal pylint errors not being affected by --disable=all?

Yep, exactly! This issue is ready for a contributor to tackle.
