Could someone please submit a gerrit change for bugzilla:45550? I don't have access to this right now, but the namespace is starting to be used on pt.wikipedia.org (and maybe other Portuguese wikis as well).
(PS: should I change my translation of MediaWiki:Scribunto-doc-page-name/pt for now?)
It's now in Gerrit. If it is merged before Monday evening, it will appear on ptwikis on Wednesday, March 27, 2013 assuming normal process.
Done merged by me now.
