New description:

 This works:
 {{{
 var('x,y')
 plot3d(0, (x,-1,1), (y,-1,1))
 }}}

 This doesn't:
 {{{
 plot3d(0, (-1,1), (-1,1))
 }}}

 It seems completely reasonable that we fix the above so it does.

Comment:

 Apply [attachment:trac_1920-verify.patch].  I couldn't find a better place
 to add this... and if someone knows that this is already tested, please
 let me know.  I did a grep through the Sage library for plotting the 0
 function, but of course if it is more like my test, then one could never
 find it.
