I've encountered a strange error in the process filter and it also said
"HTTP/0.9 How I hate thee!" although my server is not 0.9.
I found a bug of mis-detecting of a version (1.0, 1.1 or 0.9) of response.
This bug appears on the first call of the process filter with a
string data which does not have complete line (it means without \n).
In my case, process filter was called with string data: "HTTP/1.".
Therfore url-http-wait-for-headers-change-function<f> judged
the response is not http 1.0/1.1 before first line is completed.
Here is a example patch to fix this.
