vc-git: workaround for "file unregistered" problem

[David Reitter]

I've been having some problems with git:

In some circumstances, git fails to report the status of files and pretends 
they are unregistered.  One symptom can be that vc-git will try to add the file 
a second time.   I have inquired about this on the Git list [1], but received 
no response - I'm not sure if this is a bug in git.  

Either way, specifying full paths works around the problem, and the patch below 
does that for those who encounter similar issues.
