Can someone summarize again a *correct* recipe to see the bug?  What
with the wrong initial bug report, and the imprecise follow-up, I can't
figure out where the problem lies.  If I do

mkdir foo
cd foo
mkdir RCS
echo initial > file
ci -u -t-foo file
[Edit file in root]
emacs-24.0.96 -Q file
C-x v v

Then I get a prompt saying

  File has unlocked changes.  Claim lock retaining changes? (yes or no)

If I type yes, the changes are still there.  What's the problem?
