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".
