At first, I thought: "I certainly have changed at least one of them" (such
`org-log-note-headings' for which I changed the `state' string to "State %-12S
-> %-12s %t" -- as I prefer the FROM -> TO presentation of state changes).
Though, FWIW, no, these are still the original values in my case as well.

I thought that users never ever could change constants. But the docstring of
`defconst' indeed tells that "this constancy is not actually enforced by Emacs
Lisp". Though, can we be sure that this will stay true?

OK for me.
