This will be needed for this to be compatible with the JSON-based ARB
reformatter, which requires all lists to be of equal length in order for
whitespace to line up.
For example, `app_de.arb` has a few keys that do not:
```
../lib/l10n/app_de.arb - checking 261 strings
../lib/l10n/app_de.arb HAS ERRORS:
Invalid key: l_credential
Invalid key: @l_credential
Invalid key: s_credentials
Invalid key: s_delete_credential
Invalid key: s_credential_deleted
Invalid key: p_warning_delete_credential
```
