Respect new lines between case statements

[pmccloghrylaing]

The current behaviour removes any new lines between case statements, so it converts:

switch (value)
{

    case 0:
        break;


    case 1:
        break;

}

to:

switch (value)
{
    case 0:
        break;
    case 1:
        break;
}

I think it should maintain an extra space, just like between statements in a block:

switch (value)
{
    case 0:
        break;

    case 1:
        break;
}

I'm on board with this idea. I just checked prettier, and they maintain the extra line between cases statements if it exists.
I can't think of a good reason why we shouldn't do the same.

Should the same apply to switch expressions?
e.g.

var newState = (GetState(), action, hasKey) switch
{
    // Open/Close
    (DoorState.Closed, Action.Open, _) => DoorState.Opened,
    (DoorState.Opened, Action.Close, _) => DoorState.Closed,

    // Locking
    (DoorState.Closed, Action.Lock, true) => DoorState.Locked,
    (DoorState.Locked, Action.Unlock, true) => DoorState.Closed,

    // Do nothing
    (var state, _, _) => state
};
