+Subject: Include the Debian version in our identification
+
+This makes it easier to audit networks for versions patched against security
+vulnerabilities.  It has little detrimental effect, as attackers will
+generally just try attacks rather than bothering to scan for
+vulnerable-looking version strings.  (However, see debian-banner.patch.)
