[Bug] X-Accel-Redirect

[rovervr]

If you'd use an url with a filename that contains an '%' the client
should always encode it to '%25' which would get decoded correctly in
this case. 

In RFC1738 the '%' is an "Unsafe Character" and should always be encoded
in URIs

The check could be extended to something like %([a-f0-9]{2}) but
directories or files like %ears or %b1blabla would fail that check, too.
