Yes, both should be true. Fixed on trunk.

Changed to #f and the same example with "0i" added as #t.

One of the oil men in heaven started a rumor of a gusher down in hell. All
the other oil men left in a hurry for hell. As he gets to thinking about
the rumor he had started he says to himself there might be something in
it after all. So he leaves for hell in a hurry. --Carl Sandburg
