Hi Eli,

Ops sorry non-nil. It does not render well when lines are not truncated.

I don't know if would be acceptable to force trucate-lines non-nil by
default for objects.texi.

I think is not possible to show the DAG in a table but we could describe
it with a table like:

| type    | derived types                   |
|---------+---------------------------------|
| integer | bignum fixnum                   |
| symbol  | keyword boolean symbol-with-pos |
...

Maybe is more readable? I'm not sure ATM what's the best option.
