Summary: pade interfered with by taylor

Initial Comment:
(C1) taylor(sin(x),x,0,3);
(D1) x-x^3/6
(C2) pade(d1,2,2);
(D2) [6*x/(x^2+6)]

Fine so far.

(C3) taylor(x,x,0,3);
(D3) +x
(C4) pade(d1,2,2);
(D4) [6/7]

What's this?!  Pade is being affected by the Taylor 
calculation in C3?!  Presumably there is some global 
flag being set but not reset....

(C5) taylor(exp(x),x,0,3);
(D5) 1+x+x^2/2+x^3/6
(C6) pade(d1,2,2);
(D6) [6*x/(x^2+6)]

Somehow that restored the thing that was causing the 
problem.
