bug#7663: 23.2; duplicate entries in vc-dir-mode (Windows) due to backslash from svn output

[Vagn Johansen]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
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.  If you can, give
a recipe starting from `emacs -Q':

Inv vc-dir i commit changes a file i subdirectory. After the commit I
have a duplicate entry:


VC backend : SVN
Working dir: c:/dev/proj/sandbox/
Repository : http://albatross.rd.evalesco.com:81/svn/sandbox

                         ./
                         dummy/
    up-to-date           dummy/ddd
    edited               dummy\ddd



I use SlikSvn on windows which outputs backslashes in svn commands.



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'.
For information about debugging Emacs, please read the file
c:/tools/emacs-23.2/etc/DEBUG.
