Yes, this is exactly the behavior change.  It intends to make it clear
that to use dnsmasq for local dns query, one has to set explicitly
localuse to 1.  And with localuse being 0, /etc/resolv.conf will
default to /tmp/resolv.conf.auto as setup by /etc/init.d/boot

The argument is mainly that resolvfile being /tmp/resolv.conf.auto
should not have a consequence on the content of /tmp/resolv.conf.
resolvfile is dnsmasq specific and /tmp/resolv.conf is for all other
processes in the local system

Should have made it more clear in the commit message that this can
break existing expectations.  Sorry about that, I will drop this
change, amend the first, then send another version.

Thank you,
               yousong
