doc buglets?

[Rustom Mody]

Poking around in help() (python 3.4.2) I find

* PACKAGES
does not seem to have anything on packages
* DYNAMICFEATURES
seems to be some kind of footnote
* SPECIALATTRIBUTES
has 'bases' and 'subclasses'. It seems to me a more consistent naming
for OOP would be in order.  These are the OOP-metaphors I am familiar with
- superclass ↔ subclass
- base class ↔ derived class
- parent class ↔ child class

[Yeah if this is a bug its more than a docbug.
So no, I am not suggesting changing the actual attribute names which would be a 
breaking change, just the stuff in help()
