You are right, adding either of the two settings to the minimal .emacs
doesn't change anything, it still works.
I'm on:
GNU Emacs 24.0.50.1 (i386-apple-darwin11.1.0, NS apple-appkit-1138.00)
of 2011-08-24 on iancumac.local
Org-mode version 7.7 (release_7.4.1639.gd203.dirty)
The interesting thing though is that it works now with the normal
configuration, after removing the setting, even though it shouldn't have
any effect.
Thanks,
S.
