If you know of a site that that does it, let me know. EDIT: I think I might have found a trick. I'll give it a shot tomorrow.
But that is suboptimal. I'd love to see if someone is doing it right, and I'd try to do the same. I haven't really looked into it, but I will now. There may be a nice way to set up an equivalent to the two spaces which would require much less effort. He is that fallen lance that lies as hurled,
That lies unlifted now, come dew, come rust,
But still lies pointed as it ploughed the dust.
If we who sight along it round the world,
See nothing worthy to have been its mark,
It is because like men we look too near,
Forgetting that as fitted to the sphere,
Our missiles always make too short an arc.
They fall, they rip the grass, they intersect
The curve of earth, and striking, break their own;
They make us cringe for metal-point on stone.
But this we know, the obstacle that checked
And tripped the body, shot the spirit on
Further than target ever showed or shone.
