I've just pushed a patch (24301c8148f5f3220d7e597c73a59551cfa10eea) 
which fixes this bug, and also uses ---ignored, because that's how the 
Jonathan wrote it.

Do we still care about CentOS 6? The previous message in this discussion 
has been more than 2 years ago.

If so, we can remove --ignored from the call in vc-git-state, it's not 
hugely important there. It will be more important when we decide to 
reimplement vc-git-status-files in the same fashion, though.

1. Open vc-dir for the repository with an unregistered file.

2. Open the file in Emacs, modify, save.

3. See it become `up-to-date' in the vc-dir buffer.

4. Switch to vc-dir, press `g'. See it become `unregistered' again.

Apparently, in part it's a result of how bug#11757 was resolved (see the
comment at the top of `vc-git-state'), but I don't remember seeing this
problem before Emacs 25. Yet I don't see anything specific among the
recent changes that caused it.

Maybe `vc-git-state' should call `git status --short' instead of `git
diff-index'.
