Referer module: fixed regex matching against HTTPS referers.
When matching a compiled regex against value in the "Referer" header field,
the length was calculated incorrectly for strings that start from "https://".
This might cause matching to fail for regexes with end-of-line anchors.
Patch by Liangbin Li.
