utils/macros.h (N): Properly parenthesize the argument.

WTF?  How did I write this wrong?

Fortunately, I don't think it actually matters.  The argument must have
array type.  Postfix operators are higher precedence, so that's not a
problem; prefix operators are in the right place already; and binary
operators don't yield array types.
