Version control: registered or unregistered?

Question

I'm a bit confused when writing code using the VC interface. After executing the following commands in the shell (committing a dummy file ~/test/file in a fresh git repo ~/test):

cd
mkdir test
cd test
git init
touch file
git add file
git commit -am "test"

I end up in a situation in which Emacs (vc-state "~/test/file") evaluate to unregistered but (vc-registered "~/test/file") reports the converse as it evaluates to t. What's wrong?

Answer 1

Apparently, I'm supposed to be on the buffer. Hence, the following snippet

(with-current-buffer 
  (find-file-noselect "~/test/file") 
  (vc-state "~/test/file"))

is evaluated to up-to-date.
