I get a warning with all versions of nmap (including 3.81) when I run
this command:


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. 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.
