Don't de-indent case and default statements

This commit changes the formatting of a `switch statement from

    switch(x) {
    case 1:
        //stuff
    case 2:
        //stuff
    default:
        //stuff
    }

to

    switch(x) {
        case 1:
            //stuff
        case 2:
            //stuff
        default:
            //stuff
    }

Note the indentation is not decreased for `case` and `default` statements.

I know others will likely disagree with this style preference but I couldn't figure out how to control this at runtime in my init script or keymap file.

Is there a way to add this change at runtime or add a preference so I wouldn't have to maintain a fork and keep it up to date with upstream changes?
