I think I saw the same thing. I twice lost my work. I had a buffer
(c++ code) that was not under version control. I hit C-x v i. xemacs
did NOT notice it was now under vc (no update of modeline). I
reported this previously.
Later, I lost all my changes. I think I hit C-x C-q, but I'm not
certain. This has happened twice within the last week.
