There is no mention in -[NSDocument fileURL] documentation, nor in 10.5 or 10.6
release notes, that this property is observable using KVO. But when I added
some code to do this, created a document, and renamed the document in Finder
while the document was open, my observer logged a hit.
Is there some underlying or other documentation I don't know about?
