Hi,

[I tried to send this report earlier, though it seems something went
 wrong.  If it did already show up: sorry about the noise].

Recently, I get an error every time I open a new file in my document
folder due to `vc-git-conflicted-files'.  The function was introduced
in

     revno: 117697
     committer: Eric S. Raymond <esr@thyrsus.com>
     branch nick: trunk

     message:
       Integrate Rüdiger Sonderfeld's code for detecting 
       conflicted files under git.

Background: My document folder is stored in a git annex direct-mode
folder (see http://git-annex.branchable.com/).  git annex is used for
keeping folders in sync across computers, and is build on top of git.
In my particular setup (direct mode) "git status" returns nil (or an
empty string).  However, `vc-git-conflicted-files' expects it to
return a non-trivial string.

The attach patch addresses this by checking that git status did in
fact returned non-nil.

Please let me know (preferably with wide reply) if you want me to fix
the problem in some other way.

I have signed papers to FSF.

Thanks,
Rasmus
