Subject: 23.1; vc-dir with git uses wrong base directory
Date: Wed, 19 Aug 2009 15:23:38 -0600

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 <at> 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 git working tree.

I ran vc-dir on a subdirectory of this tree.

In *vc-dir*, I go to an edited file and type '='.

Emacs says: No changes between working revision and workfile

However, if I look at *Messages*, I can see from the "Finding changes"
output that VC is examining the wrong file -- the subdirectory's name
appears twice in the computed file name.

E.g., the message says:

Finding changes in /home/tromey/gnu/archer/archer/gdb/gdb/mi/mi-cmd-var.c...

... but no such file exists, the file is actually called

    /home/tromey/gnu/archer/archer/gdb/mi/mi-cmd-var.c

(one less "gdb" in there)


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.
