The current tree already has this functionality, though the code which
implements it is somewhat different. It certainly provides a
DNSMASQ_REQUESTED_OPTIONS variable containing a comma-separated list of
decimal numbers.

Best to look at the current code, and submit a patch if it doesn't
behave as you expect.
