  134.     Important note about TEClickLoopProcPtr and WordBreakProcPtr
  135.  
  136.     At one point these were defined as returning the function result in the 
  137.     condition code Z-bit.  This was correct, in that it was what the 68K
  138.     implementation of TextEdit actually tested.  But, MixedMode had a different 
  139.     idea of what returning a boolean in the Z-bit meant.  MixedMode was setting
  140.     the Z-bit the complement of what was wanted.  
  141.     
  142.     Therefore, these ProcPtrs have been changed (back) to return the result in
  143.     register D0.  It turns out that for register based routines, 
  144.     MixedMode sets the Z-bit of the 68K emulator based on the contents 
  145.     of the return result register.  Thus we can get the Z-bit set correctly.  
  146.     
  147.     But, when TextEdit is recoded in PowerPC, if it calls a 68K ClickLoop
  148.     or WordBreak routine, register D0 had better have the result (in addition
  149.     to the Z-bit). Therefore all 68K apps should make sure their ClickLoop or
  150.     WordBreak routines set register D0 at the end.
