OK, please check it in.
Attached patch updates poly.txi to reflect this change. Should there
also be a @DOCSTRING(polyinteg) in there?

@section Derivatives and Integrals
Octave comes with functions for computing the derivative and the integral

both return new polynomials describing the result. As an example we'll
compute the definite integral of @math{p(x) = x^2 + 1} from 0 to 3.
@example
c = [1, 0, 1];
-integral = polyinteg(c);
+integral = polyint(c);
area = polyval(integral, 3) - polyval(integral, 0)
