Thanks for all your ideas guys, I really appreciate the help. Finally 
got some time to try all of your suggestions, though backwhacking (\) 
the space and/or the quotes makes no difference so I decided in the end 
to stop fighting the quoting wars and to just use /etc/start_if.ath0 
which works perfectly. Not quite as neat as having everything live in 
/etc/rc.conf but it does the trick.
