Nearly neat! Doesn't work on this dialog.
Also, searching the image for the dialog text doesn't give any hits.
I think this code is in the VM, as on my Mac I don't get this dialog.
I was hoping some VM guru would answer my question,  pointing me to 
some Squeak.ini setting (e.g. QuitDialogString=Quit Squeak without 
saving?, or AskToSaveOnQuit=0).
