That is certainly nicer. Not sure how we can make this happen since it's 
just a regular Maxima list. We don't have the lisp concept of a 
pprint-dispatch table for printing Maxima objects. If we did and if we 
made the plot options a structure or some other unique thing, we could 
print it nicely.

The funny value for gnuplot_preamble is because |stringdisp| defaults to 
|false|. Long ago I used to set |stringdisp| to |true| in my init file, 
but that caused other weird things to happen so I stopped doing that. 
Perhaps it would be good to set |stringdisp| to true and fix the quirks. 
I don't remember what they were though.
