RICHEDIT_CLASS20A is provided by riched20.dll, not riched32.dll.  The 
windows 2000 implementation uses riched20.dll to implement riched32.dll 
  (ie. moves the richedit code to riched20.dll and implements the 
RICHEDIT_CLASS10A class using the new RICHEDIT_CLASS20A class.

In short, the existing code registers the correct class name, but we 
need to make a new dll dlls/riched20, and do alot of work on the 
richedit control :)

Actually, since we need to work on riched20, we might as will implement 
that properly, rather than trying to reuse the edit control.
