There is a historical issue here. Once is_local in gnome-vfs returned
true for all file: uris. A lot of code in nautilus relied on this for
things like "has local pathname", "is reasonably fast" etc. Then for
some reason this changed to return false for NFS filesystems, and a lot
of things broke in nautilus. Since then we've slowly changed to use
various other ways to decide these things. Its pretty messy still
though...
