Style: Indent level in switch blocks

[PikalaxALT]

Variant A: Case labels flush with the switch statement. This is the standard in pret/pokeruby etc.

switch (state) {
case 0:
    // ...
case 1:
    // ...
}

Variant B: Case labels indented by 1.

switch (state) {
    case 0:
        // ...
    case 1:
        // ...
}

Variant A is better due to how many nested switch statements are in the code. The alternative would be to have the deepest indent in large essential functions be 3-4 indents deeper than they would have been sticking with variant A, which makes the code less readable. Then for consistency we should keep the rest of the code on the same style.

I have made several PRs converting style A into style B, which have been approved and merged, and during original style guide discussions, we did decided on style B, so imo style B is better, plus, I prefer it because I personally find it much easier to read

I prefer style B.

Style A reinforces the fact that the case labels have no scoping significance and have about the same effect as a goto label. It's also wasteful to add an indent level when unnecessary.

I abstain from this discussion.

There is actually a third variant C: case labels indented by 1, but case contents not indented.

switch (state) {
    case 0:
    // ...
    case 1:
    // ...
}

I only mention this because this is the default in Notepad++. With that, I want to mention that editors are inconsistent as to which style they automatically indent to:

Editor	Default behaviour	Toggleable
Notepad++	Variant C	Unknown (Discussion 1, Discussion 2)
Eclipse (yes this isn't C I know)	Variant A	Yes, see image below
Visual Studio Code	Variant B	Yes? (Issue which proves its existence in vscode-cpptools extension)

For eclispe:

objectively bad

It's like the worst of both worlds

I prefer style B.
