This works nicely, thank you! Never knew about these.

By the way, I got the STARTUP to function. Turns out it's enough to set
truncate-lines variable and the change is picked up automatically (docs
say: "Calls these functions when changed: (#<subr set-buffer-redisplay>)").
Here is the code shall someone need it:

(eval-after-load 'org
  (lambda ()
    (setq org-startup-truncated nil)
    (push (list "truncate" 'truncate-lines t) org-startup-options)
    (push (list "notruncate" 'truncate-lines nil) org-startup-options)))

Note that (setq org-startup-truncated nil) is needed for the notruncate
option to work. Plus the stuff in the org-mode-hook runs after the STARTUP
lines, so beware that it can also cause interference.

Thanks all!
