Yes, I found the filter solution. Whilst that's fine for fixing up user-
generated problems, this new problem comes out-of-the-box in 2.2. It feels
like there should be a solution along with it.
Your suggestion is much better than mine. New patch added that allows
`request.headers['foo-bar']` to be looked up in templates as `{{
request.headers.foo_bar }}` without inelegant double storage.
