o Nmap now understands the RFC 4007 percent syntax for IPv6 Zone IDs.

Browse Source 
On Windows, this ID has to be a numeric index.  On Linux and some
  other OS's, this ID can instead be an interface name.  Some examples
  of this syntax:
    fe80::20f:b0ff:fec6:15af%2
    fe80::20f:b0ff:fec6:15af%eth0

This was a lot simpler than the method I previously implemented and posted
to nmap-dev.  Now I just extract the zone ID from the already available
getaddrinfo() data rather than parsing it out myself.
