The problem is not the conversion to TeX, but rather a strange way of
storing that in OutputForm.
(12) -> (eq1 :: OutputForm) pretend SExpression
(12) (= ((PRIME f ",,,") x) (^ x n))
Wouldn't it make more sense to store it as (PRIME f 3) and let the
Formatter deal with how it is shown? Here eq1::OutputForm does too much.
In other words, I would be in favour of moving the code
add_prime(a : %, s : %) : % == convert [eform 'PRIME, a, s]
prime(a, nn) == (s := new(nn, char ","); add_prime(a, sform s))
away from OutputForm and simply say something like
prime(a, nn) ==
if a is of form (PRIME x n) then
(PRIME x n+nn)
else
(PRIME a nn)
Then i-output.boot or the various Formatters would have to deal with
translating that s-expression into something nice.
