Description

Closes #6888.

We could also use an if statement to check whether the option is init-hook and and then not strip the newlines. But that introduce additional overhead, while this makes pylint faster. The fact that the rest of the test suite passes makes me think that this will be fine. We strip most options of whitespaces in other places anyway.

If this regresses after 2.14.2 we can simply add the if statement as desired.

I think this king of option is impossible to test with the config functional test framework.

[Pierre-Sassoulas]

Shouldn't the result.json change ? Probably not as init_hook are treated as a special case before the config is instanced, so we should probably create a unit test with multiple print so we can actually check that the code of each line was executed.

[DanielNoord]

This raises a SyntaxError and fails the test without the changes in the PR. So it is actually a test against the reported issue: multi-line init hooks became syntactically incorrect code.
