How strange, it's left out the bit I copied from a terminal window.
The bit I was quoting should have said :
>If the server finds the address the client is requesting, and that
>address is available to the client, the server will send a DHCPACK.
>If the address is no longer available, or the client isn't permitted
>to have it, the server will send a DHCPNAK. If the server knows

The key bit there is "If the server knows nothing about the address,
it will remain silent", so simply commenting out any range statements
should be sufficient for the server to silently ignore any requests.
It will still respond to requests from hosts with fixed addresses,
and it will still NAK requests for addresses outside the subnet.
