When symlinks are involved it gets really messy.

For example: here is an additional problem I encountered:
`dired-rename-subdir' sometimes doesn't even handle our buffer because
`dired-fun-in-all-buffers', which is built on `dired-buffers-for-dir',
doesn't consider symlinks at all: For `dired-buffers-for-dir' a buffer
that visits some DIR under a different name is simply not visiting DIR.

Other problems are: our buffer could visit a file under a now dead link.
The file renamed could have been moved from behind a link to some
completely unrelated place.  Our buffer could dired a subdirectory of a
renamed directory (this case is currently completely ignored).

I feel a bit lost.  Fixing this would be nice, at least the cases where
this is possible, but it's really complicated and I don't even know the
dired code very well.

Michael.
