works in git"

Hi.

I found a possible bug:

Running M-x vc-revert from a buffer displaying a GIT-versioned file
with non commited changes gives a message like this, for each modified
file:

FILE: needs update

I.e: If the only modified file, wich I want to revert is program.c i get:

program.c: needs update

If there are more modified files, the message lists all them (I'ts the
same message if I run M-x vc-revert from program.c, program.h or
*vc-dir*).

program.c: needs update
program.h: needs update

Removing a line from vc-git.el appears to fix the problem.  This line
was added after 23.1 but before 23.2.  23.1 didn't gave this problem.
Here is the "patch" than removes the lines (Made againsting the BZR
revision 100413):

=== modified file 'lisp/vc-git.el'
*** lisp/vc-git.el      2010-04-21 02:05:24 +0000
--- lisp/vc-git.el      2010-05-22 18:43:28 +0000
*************** or an empty string if none."
*** 577,583 ****
    "Revert FILE to the version stored in the git repository."
    (if contents-done
        (vc-git-command nil 0 file "update-index" "--")
-     (vc-git-command nil 0 file "reset" "-q" "--")
      (vc-git-command nil nil file "checkout" "-q" "--")))
