Yet, this is easy to reproduce. Invoke emacs 21 with -q, then
C-x d /tmp RET
M-! touch 00a RET
g --> Now yu should see a file named 00a
C-x C-q
undo --> Now you don't see the file 00a any more
it was useful when I updated a dired buffer with 'g' without looking at
it first, and wanted to look at its old status. Very handy in some
situations.
