I cannot reproduce this.  If the buffer `foo' is in Fundamental mode,
I get precisely what the manual says.

Your output suggests that the buffer with the text has font-lock
turned on.  Please see how could that happen in Fundamental mode.

That is normal behavior.

No, it's expected behavior when the buffer was fontified.
