1. M-x vc-directory gives me a list of changed files in current
   directory and one sub directory.

2. I marked all files, then `v v', it prompts this in the minibuffer: 

,----
| All members of a fileset must be under the same version-control system.
`----

The directory is a svn repo. I can do the above successfully on the
shell command line.

,----[ M-x emacs-version ]
| GNU Emacs 23.0.50.4 (i386-apple-darwin9.1.0, Carbon Version 1.6.0) of 2008-01-24 on zen

Were some of the files that you selected unregistered? If yes, then the
error you get is expected (although the wording could be improved to
make it more clear).

BTW, I think there's a fundamental error in VC's handling of backends,
right now:  The backend should be a buffer-local property, not
a file-local property.

So what happens with files that are not in any buffer (like probably a
lot of files that would appear in vc-dired)?

Huh?  If they're in vc-dired, they're in a buffer.
That's the whole point: it ensures trivially that all the files selected
in a vc-dired are treated by the same backend.

There seems to be a misunderstanding here. Why would the files be in a
buffer? One can edit something, quit emacs and then 2 weeks later run
vc-dired.  It's possible that none of the files that vc-dired shows to
be in a buffer.

But any VC operation is run from a buffer.  Either a file buffer or a VC
buffer.  The backend to use should depend on the buffer, not on the (set
of) file(s).

Well, for vc-dired different files can belong to different backends. If
you are saying that its not a good idea, then we are in complete
agreement.

No, I'm saying that in order for VC-dired to make sense when files can
belong to several backends, the "current backend" should be per-buffer
rather than per-file.

So you can have a VC-dired buffer in CVS mode on /foo/bar while having
file /foo/bar/baz in another buffer and switching between CVS and RCS
backends in that buffer.

No, they are all already registered. 

I found the cause, it is because i have sort directory first in dired
buffer. Namely, I have the following in my .emacs: 

,----
| ;; Sort directories first
| (defun sof/dired-sort ()
|   "Dired sort hook to list directories first."
|   (save-excursion
|     (let (buffer-read-only)
|       (forward-line 2) ;; beyond dir. header
|       (sort-regexp-fields t "^.*$" "[ ]*." (point)
|                           (point-max))))
|   (set-buffer-modified-p nil))
| 
| (add-hook 'dired-after-readin-hook 'sof/dired-sort)
`----

Can VC Dired Mode handle this case?

This seems to directly modify the dired buffer, so probably something
goes wrong there.

If you can reproduce the problem starting from emacs -Q without the code
above, the please report back.

Also vc-dired is very likely to get replaced soon...

No, it doesn't happen with -Q or simply by removing that hook.

Okay, then I will fall back on the command line at the moment..
