New description:
In Sage 4.1, the category of a category was changed from Objects() to
Sets(). I.e. we used to have:
{{{
sage: Groups().category()
Category of objects
}}}
And now we have:
{{{
sage: Groups().category()
Category of sets
}}}
The attached patch reverts this, in particular because the
objects of Sets() are exactly the parents.
