Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

I have uniquify-buffer-name-style set to post-forward, which means that
I expect buffers with the same name to be called BUFFER|DIR.  This
doesn't quite work with vc-dir: the DIR part corresponds to the setting
of `default-directory' in the buffer where I invoke the command, instead
of the directory I specify.

To reproduce, start "emacs -Q" and evaluate:

(progn
  (require 'uniquify)
  (setq uniquify-buffer-name-style 'post-forward)
  (cd "/tmp")
  (make-directory "foo")
  (make-directory "bar")
  (vc-dir "/tmp/foo")
  (cd "/tmp/foo")
  (vc-dir "/tmp/bar"))

You will get two buffers, "*vc-dir*|foo" displaying /tmp/bar, and
"*vc-dir*|/tmp" displaying /tmp/foo.

I tried to fix this by binding default-directory around
create-file-buffer in vc-dir-prepare-status-buffer, which partly fixed
the problem: the buffer for bar had a correct name, but the buffer for
foo was still "*vc-dir*|/tmp".

If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/usr/local/share/emacs/23.0.92/etc/DEBUG for instructions.

In the particular case of shell that would not cause trouble anyway;
shell for the same buffer name just pops to that buffer, and C-u M-x
shell calls `generate-new-buffer-name' and bypasses uniquify. AFAICS,
eshell does the same thing (C-u M-x eshell brings a "*eshell*<2>"
buffer).

But this is all best left post-release, for the introduction of a new variable.

I'm closing this bug now, as the patch is already installed.
