At the end of the text the cosmetic changes script is adding unnecessary newlines:
```
python pwb.py cosmetic_changes.py -ns:0 -family:wiktionary -lang:cs -start:\! -summary:"cc" -simulate
ATTENTION: You can run this script as a stand-alone for testing purposes.
However, the changes that are made are only minor, and other users
might get angry if you fill the version histories and watchlists with such
irrelevant changes. Some wikis prohibit stand-alone running.

It seems that `textlib.replaceLanguageLinks` is causing this so maybe it's not a cosmetic changes related problem but more general.
