  	set arrow from graph 0, first <y1> to graph 1, first <y2> nohead

does that quite nicely.

Not at all.  Express the line as a function and plot it.  Done.

Not unless you also want to add a term->draw_infinite_line() entry to it 
while at it.  term->clip_region is for clipping primitives.  Infinite 
lines aren't terminal primitives, and as long as they aren't, it's none 
of term->clip_region()'s job to clip them.
