The result of formatting:

exampleFunction : {A : Type} -> List A -> List A -> List A -> List A -> List A -> List A -> List A -> Nat;

is currently:

exampleFunction : {A : Type} -> List A -> List A -> List
      A -> List A -> List A -> List A -> List A -> Nat;

This type signature would be clearer if there was no line break between List and A.

Use APE mechanism to format Function expressions (#1852)
791666f 
I paired with @janmasrovira on this work.

Before this change - long type signatures were formatted to contain line
breaks within applications:

```
  exampleFunction : {A : Type} -> List A -> List A -> List
        A -> List A -> List A -> List A -> List A -> Nat;
```

After this change we treat `->` and an infix operator and format like
other infix applications:

```
  exampleFunction :
    {A : Type}
      -> List A
      -> List A
      -> List A
      -> List A
      -> List A
      -> List A
      -> List A
      -> Nat;
```

* Fixes #1850
