// waiting for 4 ratings
// waiting for 5 ratings
// waiting for 6 ratings
//
// - case 2
// this should be fine since it has been translated and the blocks
// have been removed i.e. block.tr.php won't be called anymore
//
// - case 3
// this will leave everything as is. this will work as well, but only if
// there is no {$var} in the string - see case 1
// --- xing
// if the entire string in is a variable, we pass it on to block.tr.php
// e.g. {$menu.menu_title} in top_bar.tpl
// if you change this regexp, please modify the one in languages/BitLanguage.php as well (approx line 256)
