Bessel_J or %J ??? Maxima not consistent #1550

Maxima appears to use *both* the notation Bessel_J[i] (x) and %J[i](x) to denote the Bessel J-function.

Bessel_J is used only in the file bessel.lisp, and %J everywhere else (comm, hyp, hypgeo, ode2).

Could we unify these? Or is there some reason to keep them separate?

Don't know the history, but it's been that way for as long as I can remember.

I think we should unify them to just one or the other.
Bessel_J is better because it's more explicit, but %J is closer to the typical math notation.

Unify.

Per discussions on the mailing list, I think bessel_j is the preferred notation.

I think these are fixed now, and bessel_j(n,x) is the preferred notation.
