I don't know how useful that command is, since it covers 2,147,483,648
IPs. I hope you have a long time to wait for results :). Also, as
someone else on nmap-dev mentioned, the 10 is kinda pointless for
anything below /4. 0.0.0.0/1 scans the same IPs.
I looked into the issue though, and found and integer overflow. I
changed TargetGroup::ipsleft from an int into an unsigned long and that
command now works appropriately. The change will be in the next version.
/0 still doesn't work, so I added an error message if someone tries it.
