As I write in <http://lists.squeakfoundation.org/pipermail/v3dot9/2006-February/000233.html>
this method was present in older images, I only re-added it.

I don't think so. All subclasses of TextAttribute implement
#emphasizeScanner:. There would be no point in having the
TextAttribute class, if it does not implement #emphasizeScanner:. The
#emphasizeScanner: method is like the #accept: method in the visitor
pattern. If it is not there, the object is simply ignored.
