Summary: Need to specdisrep more systematically

Initial Comment:
There are lots of places where the Poisson 
representation isn't handled properly, and a few where 
Rat isn't handled properly.

I'm not sure if anyone cares about Poisson 
representation, to tell the truth, but it would be nice if 
specrepcheck were used more consistently....  Of 
course, it would be even better if representation-specific 
routines were called, but we can start with 
specrepcheck.

For example:

   diff(rat(x),rat(x)) => 1 OK
but
   diff(x,rat(x)) => 0  BAD

diff(intopois(U),U) => fatal error
taylor(intopois(sin(U),U,0,3) => fatal error
ratsimp(intopois(sin(U))) => internal error
