+		0=Debug off; 1=Print errors on console; 2=Print debug information
+		on the console.
+
+		Debug output is generated with syslog.  The editor works on
+		/dev/console.  In order to get both a usable display and also
+		readable debug output, syslog'ing should sent to some device other
+		than /dev/console (which is the default).
