Fix the handling of URIs containing %2F when AllowEncodedSlashes

is enabled.  Previously, such urls would still be rejected with
404.

(original CHANGES entry tweaked to remove mention of status code;
404 is what you get with AllowEncodedSlashes Off, but with the
broken AllowEncodedSlashes On processing you actually got 400)
