[Coco] Undocumented Nitros-9 updates

[Diego Barizo]

Some of Nitros-9 commands have been updated from their OS-9 counterparts 
(Like dsave and tmode).
I would like to do a small guide with the new format and options for 
those commands.
Is there any other besides those 2 that has been updated?

(I know that the new formats have been explained more than once, but I 
would like to put all the information together in one place)
