Actually #printOn:base:showRadix: will fail for any showRadix: false 
unless base is 10. Sounds weird? Yeah. Here are examples:

   100 printOn: Transcript base:  8 showRadix: false "->fails"
   100 printOn: Transcript base: 10 showRadix: false "->succeeds"
   100 printOn: Transcript base: 16 showRadix: false "->fails"

Looks like #printStringRadix: is supposed to return a radix whenever 
invoked but doesn't. Note how it is actually special-casing radix 10 - 
it looks like it's expecting #printStringBase: to add the "16r" prefix 
which apparently #printStringBase: doesn't (or rather "no longer") do.

BTW, this is a classic screw-up that tests would have found in no time. 
Where are they when you need 'em?
