This isn't exactly a bug as such, but rather by design so you can say
"Scan this host and it's entire network segment". It's really rather
nifty if you have more complex netmasks than the 24-bit variant and you
just don't feel like figuring out the network address.
Although nmap should remove duplicates, so the monster output that ended
your original mail is a bit weird.
