Title: Fixes broken references on Ruby v1.9.x

Calling to_s on an array containing strings results in different output on Ruby v1.8 and v1.9:

```bash
% rvm all do ruby -e 'puts ["foo", "bar", "baz"].to_s'
foobarbaz
["foo", "bar", "baz"]
```

But `join` works the same:

```bash
% rvm all do ruby -e 'puts ["foo", "bar", "baz"].join(" ")'
foo bar baz
foo bar baz
```

So I changed the `to_s` to `join("\n")`.
