Unsupported line breaks used inside t()

Don't do the following... Make it a one liner and move the HTML outside whenever possible. POTX string extractor module does not support this type of line breaks.

      return t("<p>Break long pages into smaller ones by means of " .
               "a \"page\" tag:</p>\n" .
               "<pre>\n" .
               "first page here.\n" .
               "%separator\n" .
               "second page here.\n" .
               "%separator\n" .
               "more pages here.\n", array('%separator' => PAGING_SEPARATOR));
