Subject: bug#19386: 24.4.51; vc-git-dir-status shows edited files as up-to-date when FILES is non-nil
Date: Mon, 15 Dec 2014 16:12:45 +0200

Because the `up-to-date' stage in `vc-git-after-dir-status-stage' calls
'git ls-files -z -c -s -- file1 file2 file3', and that output includes
modified files (but not unregistered or ignored).

To reproduce:

~/vc$ git init test
Initialized empty Git repository in /home/gutov/vc/test/.git/
~/vc$ cd test
~/vc/test$ echo foo > foo
~/vc/test$ touch .gitignore
~/vc/test$ git add .gitignore
~/vc/test$ git commit -m "Add .gitignore"
[master (root-commit) e416e1c] Add .gitignore
 1 file changed, 0 insertions(+), 0 deletions(-)
 create mode 100644 .gitignore
~/vc/test$ echo bar > .gitignore
~/vc/test$ echo bar > bar
~/vc/test$ git add foo
~/vc/test$ git commit -m "Add foo"
[master 3a47057] Add foo
 1 file changed, 1 insertion(+)
 create mode 100644 foo
gutov <at> axl:~/vc/test$ touch tee
gutov <at> axl:~/vc/test$ PATH=~/vc/emacs-24/src:$PATH emacs --batch --eval "(let (done) (vc-call-backend 'Git 'dir-status-files \".\" '(\"foo\" \"bar\" \"tee\" \".gitignore\") nil (lambda (entries &optional mtc) (message \"%s\" entries) (setq done (not mtc)))) (while (not done) (sleep-for 0.1)))"
((.gitignore up-to-date [cl-struct-vc-git-extra-fileinfo 33188 33188 nil nil]) (foo up-to-date [cl-struct-vc-git-extra-fileinfo 33188 33188 nil nil]))
((tee unregistered [cl-struct-vc-git-extra-fileinfo 0 0 nil nil]))
((bar ignored [cl-struct-vc-git-extra-fileinfo 0 0 nil nil]))

The .gitignore entry above should be `edited'.

The easiest solution seems to be to move the `up-to-date' stage to after
`diff-index'. Fix forthcoming.
