Per this review comment.

As for the presentation of labels / aliases -- the current format works, but I think putting every label / alias on a separate line would make it even more visually clear. I'm saying this with the future generalization in Wikidatastuff in mind (multiple or long labels), but even here when the labels are long it can get hard to read:

en: 2. Bothnian Sea (International drainage basin Trondelagsfylkene - Sweden) | SE1102

If you happen to have an alias that's equally long, or two aliases, they might get hard to parse when they're all on one line.

Change the format of the outputted labels, ensuring that it is still easy to separate languages etc.
