tex bug and tex output for elliptic functions



When producing tex output for elliptic functions such as jacobi_sn,
what would people like to see printed?  I have a patch that will make
jacobi_sn(u,m) get converted to $sn(u,m)$; inverse_jacobi_sn(x,m)
becomes $sn^{-1}(x,m)$; and elliptic_k(p,m) is $F(p,m)$.

Without it, you get things like

$JACOBI_SN\left(u,m\right)$

which is ok, except that the underscore makes the following S a
subscript to JACOBI.

Anyone know how to fix that?
