i do this. but i did not know about +noidnout until the day when the 
defaults changed. while this was in this case caused by the freebsd 
ports team and their change to an internal ./configure invocation, i 
still think that nothing ./configure can do should change the default 
for tools. (this is how shell scripts remain portable.)

so back in BIND9 V9.10 when idn support was added, the default for dig 
should have been "backward compatibility", that is, no IDN output unless 
the user asks for it AND the libraries supported it.
