Indentation with a guard on a new line

If I just write code naturally and indent everything:

```elixir
def func(x)
when x.y = 1 do
abc
end
```
After `elixir-format`:

```elixir
def func(x)
when x.y = 1 do
abc
end
```

and now when I add something after the function, the indentation breaks:

```elixir
def func(x)
when x.y = 1 do
abc
end

def id(x) do
x
end
```

also, shouldn't the mode's formatting be at least a little bit similar to the format tool?
