Subject: [PATCH] Use wfEmptyMsg() here instead of !$tagDescription. Should
 make <non-existent-message> errors when a particular HTML tag doesn't exist
 (notably, diff-s) to go away now. Should now output the raw tag ('<s>', again
 in the noticed case). Oddly, I like that more than the messages ;-)
