Jolly good, chalk that one up to stupidity on my part; it even says as much
in the manpage:

"By default,
 Nmap sends an ICMP echo request and a TCP ACK packet to port 80."

'Ping' is being used in a slightly odd context, though - very easy to make
assumptions about nmap's behaviour which aren't necessarily true!

Many thanks,

- James.
