Yes, that patch applies cleanly.

I propose this commit message:

-----8<----8<-------8<----
Option to remove A-forA

Given the following quote, and if that trend holds true, there are probably
no significant A-for-A requests anymore.

The percentages of A-for-A seen by root servers reported in 2001, 2003, and
2008 was 12%, 7.03%, and 2.7%, respectively. The decreasing trend
continues in our data collected in 2012, where A-for-A only contributes
0.4% of the traffic.

+++ b/man/dnsmasq.8
+.TP
+.B --no-afora
+Do not treat A-for-A DNS requests special. I.e. do not duck type a FQDN to an IP.
+++ b/src/option.c
+  { LOPT_NO_AFORA, OPT_NO_AFORA, NULL, gettext_noop("Do not treat A-for-A special."), NULL },


Those text portions??
