Currently, the translation of namespace prefixes is inconsistent across pages.
I would expect that the Translate extension would support some way to translate the namespace prefix in a central location (probably a MediaWiki interface message) to maintain consistency between wikis and translated subpages.
How to reproduce:
- Install Translate extensions
- Create a translatable page in a namespace, say Help:Farming carrots
- Mark it for translation, including page display title
Observed: The full title including the namespace is translatable
Expected: The namespace is automatically translated
