If that's the concern, I'd much rather just expose a function to help
with dealing with redirects, rather than sticking a rather arbitrary
[Ascii] in everyone's Response. I think a function along the lines of:

checkRedirect :: Response -> Maybe Request

would fit the bill, and could be extracted from the current `http` function.
