Subject: [PATCH] Ensure Entities are never transformed in codemod mode.

The prior changes (in 458fe54899c942f69f26cf789fa5339627f2fa81) ensured
that **named** entities were never matched (things like `&nbsp;`) but
still allowed matching of char codes (hex or base 10).

This ensures that **no** entities can be matched.
