I was ready to give up on this patch, but then I thought, what
percentage does lost+found and dot-file-only directories cover for mount
points?  What other cases are there?

This updated version of the patch reports about dot files if they are
the _only_ files in the directory, and it suggests a top-level mount
point might be the cause.

Does this help?
