Summary: ratsimp with algebraic == true

Initial Comment:
With algebraic == true, ratsimp doesn't fully simplify 
some expressions.  Here is an example

(C1) display2d : false$
(C2) algebraic : true$
(C3) integrate(1/(2+x^3),x)$
(C4) ratsimp(diff(%,x));
(D4) 4*2^(2/3)/(4*2^(2/3)*x^3+8*2^(2/3))
(C5) ratsimp(%);
(D5) 1/(x^3+2)

Maybe this is the purpose of fullratsimp, but 
it seems odd that ratsimp fails to cancel the 
factor of  2^(2/3). I discovered this when I ran 
run_testsuite with algebraic == true.
