Summary: plot2d and plot3d options

Initial Comment:
Typo in plot2d or plot3d option name results
in Lisp error. Try

plot2d(sin(x),[x,0,3],[aaa,1]);

Ok.  We throw a maxima error instead of a Lisp error for
unknown options.

I'd like to see Maxima error but not Lisp error.
Maxima should newer dump user into lisp
prompt. Right now it is not the case. Many simple
errors are not properly handled by Maxima and
result in Lisp errors.

I don't find this to be a problem.

What do you want to happen?  Maxima just prints an message
about an unknown option?  Afterwards, should it be ignored?
 Stop?  What?
