You're right. These don't work.
We have a few options:
1. We can ignore the problem, and let `http://2/` fail to match `img-src
0.0.0.2` and match `img-src 2`.
2. We can normalize the URL, but not the source expression, and let `
http://2/` match `img-src 0.0.0.2', but fail to match `img-src 2`.
3. We can normalize both, and let `http://2/` match both `img-src 0.0.0.2`
and `img-src 2`.
4. We can throw away IP addresses entirely.
I prefer either #4 or #1. :)
