(S-PLUS 3.4 too)

There's no NextMethod in print.factor, but I was wrong on the other
example: It has NextMethod("print",....) with an explicit generic, so
I don't think it should go near the CAR(call) bit at all.

I'll take a closer look, but there's also a few other nasty bugs
nagging us at the moment, and this looks like it could require surgery
to do_nextmethod with some risk of complications.
