According to the discussion we had elsewhere, I've just removed this
additional privilege given to the desktop user, since it is not used
right now.

Understood, thanks for the clarification.

I wasn't thinking of a specific potential problem (apart of user
confusion, due to providing multiple interfaces to the same settings).
But it was not obvious to me that this would not cause any
subtle problem.

Anyway, that's not a blocker for 0.23, but the potential for user
confusion, that implies additional user support work, seems enough to
me to hide these settings in Vidalia. So, I've created #6844.
Obviously, if you disagree, we can reconsider :)

OK, code review passes, pushed two minor commits (one comment + a note
added to the blueprint) on top. Time to test!

Cheers!
