CVS code:

The routine term->layer(TERM_LAYER_BEFORE_PLOT) is called at the
start of each clause within the 'plot' or 'splot' command. So a
terminal driver could, if needed, set an internal flag when it 
receives this call and then term->filled_polygon() could test and
clear it after the first call.  

There is a corresponding call to term->layer(TERM_LAYER_AFTER_PLOT)
 at the end.  This is, of course, *after* the last polygon but if
it's a question of having the terminal do some cleanup at the end
then this should be sufficient.
