bug#4553: 23.1; uniquify gives *vc-dir* buffer the wrong name

[Tom Tromey]

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 bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

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


I have a *vc-dir* buffer opened on a directory:

    VC backend : Git
    Working dir: ~/gnu/archer/archer/
    Branch     : archer-tromey-python
    [...]

And, I have:

    uniquify-buffer-name-style is a variable defined in `uniquify.el'.
    Its value is 
    post-forward-angle-brackets

    uniquify-strip-common-suffix is a variable defined in `uniquify.el'.
    Its value is t

However, the aforementioned buffer is named *vc-dir*<testsuite>.
This is simply wrong.  I think I would expect *vc-dir*<archer>.

I managed to get one named *vc-dir*</tmp> as well.  I don't know how,
but that one was also clearly wrong, as the directory in question was in
/home/tromey, not /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/share/emacs/23.1/etc/DEBUG for instructions.
