 From http://austingroupbugs.net/view.php?id=985#c2885 (which will become
 POSIX standard once approved):
 
     The expression shall be expanded as if it were a word in
     double-quotes, except that the treatment of a double-quote inside
     the expression is unspecified and the result of parameter expansion
     of the '@' special parameter is unspecified.
 
 So the NetBSD shell is OK as-is in this regard, though it doesn't hurt
 to change the shell to treat "$(("1"))" like "$((1))" because POSIX says
 (will say) "unspecified".
