The messages are wikimedia-copyright, wikimedia-copyrightwarning, and wikimedia-editpage-tos-summary.I've contacted Siebrand and Gerard from TranslateWiki and we hope they can be made available through the translatewiki.net interface soon.
This will clutter the already messy editing interface even further by breaking the terms of use into three parts (before it was in copyrightwarning and edittools). I don't suppose this can be avoided, as edittools is customized on most wikis and cannot be changed in a centralized way, but local wikis should then be allowed to suppress wikimedia-editpage-tos-summary and move its contents to edittools (or vice versa).
