Missing line breaks in default translations

[robarov]

Description

Translations, like those in src/translations/nl/app.php are missing line breaks.

This results in Craft sending out ugly user activation/forgot password/... default mails without any line breaks:

Hallo FOO,Klik op de volgende link om je wachtwoord voor FOOBAR te 
resetten:<https://domain.com/admin/actions/users/set-password?code=
FOOBAR>Als je deze email niet verwachtte, kun je hem gewoon negeren. 

Steps to reproduce

1. Compare Line 1171 in src/translations/en/app.php and src/translations/nl/app.php
2. There are more.
