Well. I think I missed that `defconst', unlike `defvar', overrides the
existing variable value. Switching to `defvar' is ok. (Or, it might be
something like (eval-after-load 'org-macs ...), but I see no reason to
prefer it over switching to defvar).
I think it will be best to install the change in Emacs and then back-port
it to Org. Will it be ok?
