Sorry for whining. I know that documenting is not an easy job and it would
be nicer to just do something else. But for example this didn't quite tell
me what does "interior_texture" do:

"This patch simply lets you specify a separate texture for the
interior of an object. Interior textures should work in exactly the
same way as normal ones."

  I think that a more specific explanation could be good :)

How can it get more specific? It applies a separate texture to the 
interior surface of the object...the texture is an ordinary texture, and 
should layer and otherwise behave like ordinary textures.

  Aha! Interior _SURFACE_. It's not the same as the interior of an object
(which can have, for example, media).

Btw, how does it work with merged objects? And what about differences?

It uses the ray direction and the raw, un-flipped normal of the surface 
to tell between the sides, so merges should work fine. I don't know 
about differences though, they may not flip the normal properly(I seem 
to remember a discussion about this a while ago).
And before you ask, it should work fine with triangles and other plane 
primitives, since they have two separate sides, but I don't know about 
bezier patches.
