I have no practical experience of this stuff, the only clues I can see 
is that the wpad draft references RFC 2052, but RFC 2782 (which mandates 
underscores) came out after that draft expired, and explicitly obsoletes 
RFC 2052.

Thanks to the magic of a publically-archived mailing list, our 
collective wisdom is already on its way into Google....

"man syslog.conf" is your friend: dnsmasq logs queries as facility 
daemon, level debug.
