Almost-standards mode

In a remarkable show of good sense, Mozilla added the “almost-standards mode” to support XHTML 1.0 Transitional, HTML 4.01 Transitional, and a bothersome IBM system doctype. (See bug 153032, the revised doctype sniffing documentation, and the article about this.) For the first time, some of the IBM pages I use daily look perfect. And there was much rejoicing! Too bad this didn’t make 1.0, but 1.0.1 may be good enough.
