Summary: taylor: "sign called on imaginary arg

Initial Comment:
expr: atan(1/sqrt(1-b))/sqrt(1-b);

taylor(expr,b,1,2) => 
  SIGN called on an imaginary argument: %I
     (bizarrely, it says this twice....)

I suspected that this was because of %i introduced by 
using logarc on expr internally, BUT:

taylor(logarc(expr),b,1,2) =>
   works just fine
