Well, I think Justin has it right --- \dP should be just like \df, which means to list "everything". If you add the "t" or the "i", that means to list only those kinds of things (just like adding one of a, n, p, t, w does for \df). You can add both, and then it list both kinds, just like \dfanptw list the same things that \df does.
That's also what I changed the docs to say, but I failed to update the code correctly, and didn't verify the expected output closely either. So I'm due to resubmit this ...
