After a few tests, I'm confused and I don't understand all the changes
in this area (and they are not documented in ORG-NEWS.)

Let's forget about what "special" means and how properties are
displayed and set in the buffer.

We have four categories of properties:

1. those which are *never* inherited (like ITEM)
2. those which are *always* inherited (like CATEGORY)
3. those which inheritance relies on `org-use-property-inheritance'
4. those which are not part of the previous types

(4) sounds a bit borgesian, but it's important: my understanding is
that this fourth category *should* be empty.  Apparently it is not
empty, since the PRIORITY property inheritance is not controlled by
`org-use-property-inheritance'.  Are there other exceptions?

There is a default priority the same way there is a default category:
having a default value for the PRIORITY property should not prevent
inheriting it from a superior headline IMO, and the previous behavior
was right.

I know dwelling on this is boring but we need to do so, at least to
clarify changes in etc/ORG-NEWS.

Thanks,
