The accepted answer makes a good argument against those placeholders: you <em>want</em> translations to break even on small changes in the English original because the translations will probably need to reflect the change, too.  Maybe that\'s not the case right now as new stuff is being checked in pretty much every couple of hours, but in the long run, it\'ll be overwhelmingly true.</p>',
