The thing is that purely using a "VCS-centric" view of what files are available is usually _much_ more efficient. The VCS usually can efficiently tell you about an "interesting subset" (non-ignored) of unregistered files, and I think that's enough -- there's no need to read the filesystem directly. [Indeed, reading the filesystem directly would both require a lot more programming effort, and probably be much, much slower (remember that one of the big problems with vc-dired historically is that it's so slow as to be basically unusable for non-trivial projects).] -Miles -- "Nah, there's no bigger atheist than me.
