bug#2055: 23.0.60; vc-dired doesn't work right with Git

[Ian Eure]

If you run vc-dired in a directory below the top of a Git working
copy, vc-dired gets confused.

e.g.:

project-a
project-a/lib

If you run vc-dired in lib, the paths in the buffer are relative to
the root, project-a. Subsequent commands on the dired buffer fail to
run, since they pass a nonexistent path to git.

The issue seems to be that vc-dired calls git diff-index, which shows
all paths relative to the WC root rather than the CWD.
