 patch won't work.

 Right. However the editor is (still) set to output XHTML 1.0 compliant
 code so upper case tags or attributes are not valid. Expecting users that
 would type code in the HTML editor (and manually add the htmlspecialchars)
 to be aware of that :)

 On the other hand nearly all of the autop related functions/filters allow
 for upper case, so we should probably normalize the <pre> tags to lower
 case (using regex for the splits is a bit slower when there are several
 <pre> tags).

 Not sure how this is going to be handled in the future, HTML 5.0 allows
 upper case and also some of the old (HTML 3?) syntax like no closing tags
 for <p>, no self-closing, etc. Probably we will stick to all lower case
 tag names and attributes as coding standard, but follow the rest of the
 HTML 5 changes.
