[PATCH] Very minor bug in output.cc

If I attempt to do a OS or Version scan on a down host, I get this message: ron@slayer:~$ sudo nmap -O -sV -sS [insert down host] Starting Nmap 4.20ALPHA7 ( http://Insecure.Org ) at 2006-09-30 21:51 CDT Note: Host seems down. If it is really up, but blocking our ping probes, try -P0 OS and Service detection performed. Please report any incorrect results at http://insecure.org/nmap/submit/ . Nmap finished: 1 IP address (0 hosts up) scanned in 4.091 seconds Since no OS or Service detection was done, that's a little confusing, so I wrote a little patch to fix it. Ron
