The last value form in `foo2' returns `foo3'.  The last `message' call
displays "Foo2".  Calling a command via M-x doesn't use the return
value, so you see only the last message.  Note that evaluating (foo2)
also messages "Foo2" (you can see it in *Messages*), it's just covered
by the subsequent message showing the return value.
