This is more a feature request, than a bug.
When listing new pages with Special:NewPages and you moved a page, there will be written "originally created as <pagename>".
Unfortunately, this is plain text and no html-element. So there is no change to format this text with css. Or - in my case - hide it.
Is there a chance, to enclose this message with a <span>?
