[bug-diffutils] bug#33467: bug#33467: "diff" can not scan directories with same dev/inode

[Mark Raymond]

This sounds similar to a problem I have just encountered.

If I have filesystems mounted at:

    /mnt/foo
    /mnt/foo/subfs

then do

    mount --bind /mnt/foo /mnt/bar

then the contents of `/mnt/foo` and `/mnt/bar` are different, because 
`/mnt/foo/subfs` has contents but `/mnt/bar/subfs` does not have 
contents. However

    diff -r /mnt/foo /mnt/bar

returns no results. However in my case, rsync is also unable to show the 
differences.
