Re: Correct implementation of undoManagerForTextView

This made the entire undo system go haywire - e.g. hitting Undo removed the entire contents of the view, undos failed to register, or they registered but didn't enable the Undo menu item. As far as I could tell, I now had three undo managers (or three conflicting pointers to the same undo manager) - one for each delegate, plus the default manager for the main window, which was still trying to manage everything.

I just had another try at this, and managed to get it to work vis-a-vis save warnings through querying -canUndo. However, now I've got a new problem - the undos don't show up in the menu! Do I need to post them individually, say through -textView:shouldChangeTextInRange:replacementString:?
