About [[MediaWiki:Wmobile-copyright/en]]
All http:// to //, for https users
There are no fixed protocol URLs to Wikimedia projects in the strings as far as I can tell. Wikimedia doesn't make links outside of its scope protocol relative.
Oh, sorry, but I did not understand what you mean, have any adverse effect on it? If it is true, then I suggest only change http://en.wikipedia.org to //en.wikipedia.org, more user-friendly for https users, to avoid jumped out https.
Crap. I searched 3 times and didn't find that one... Sorry, I'll get it fixed...
And yes, I overthought again... MediaWiki:Wmobile-copyright/en is not a message that belongs to any current product, so there is nothing to fix here.
