From 30f867423a6cc1c0c2fea742e76aa8e288028894 Mon Sep 17 00:00:00 2001
From: Jeremy Hylton <jeremy@alum.mit.edu>
Date: Mon, 18 Sep 2000 22:50:38 +0000
Subject: Do not close socket when a Content-Length is 0.  This make the
 interface consistent: The client is responsible for closing the socket,
 regardless of the amount of data received.

Restore suport for set_debuglevel call.
