Subject: 23.0.92; vc-git loses track of the current working directory

Hi,

Consider the following directory layout of a git working copy:

a
|-- .git
`-- b
    `-- c

where "c" is a file already added into the git index.

Then, go under "b", run "emacs -Q", modify "c", and M-x vc-dir.
Emacs shows:

--8<---------------cut here---------------start------------->8---
VC backend : Git
Working dir: /tmp/a/b/
Branch     : master

                         ./
                         b/
     edited              b/c

--8<---------------cut here---------------end--------------->8---

This looks weird and most of the VC commands against "b/c" fails.
For example, when I type "i" it fails with:

  error: b/b/c: does not exist and --remove not passed
  fatal: Unable to process path b/b/c

In the minibuffer:

  vc-do-command: Running git update-index --add -- b/c...FAILED (status 128)

It looks like that vc-git should chdir to the GIT_DIR before running
"git update-index", or remove "b/" from the relative path?
