It looks like you have copied the files only. SVN history is lost now. You have to use svn move instead. Please revert this revision and commit again.
Recommitted with svn move in r91587. I hope it fits, probably cannot do better. It is after major refactoring so the diffs will be large anyway.
Looking for online diff of i18n file now produces 400 bad request on me: r1=91586&r2=91587 http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/QPoll/i18n/qp.i18n.php?&pathrev=91587&r1=91586&r2=91587
Dunno why but r1=91587&pathrev=91587 http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/QPoll/i18n/qp.i18n.php?view=log&r1=91587&pathrev=91587 looks good. Thanks a lot.
