Clarification on switch/case indentation in contributing guidelines

The contributing guideline does not specify how the switch/case block should be indented. There are two ways and both of them are used in the code:

switch (var) {
case VAL:
    break;
default:
    break;
}

or

switch (var) {
    case VAL:
        break;
    default:
        break;
}

I find personally the first option nicer as it does not unnecessarily indent the whole blocks of the code in the case while keeping the blocks still separated. Any other views/pros/cons of the solution?

Once agreed, this should be updated to the contributing guidelines.
