Surely not.  That would be:
 int x[1];
 std::copy( x, x+1, output );

What Neal wrote is perfectly legal.  See 5.7 para 4 in the standard:  
"For the purposes of these operators [+ and -], a pointer to a nonarray
object behaves the same as a pointer to the first element of an array of
length one with the type of the object as its element type."
