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. _______________________________________________ emacs-pretest-bug mailing list emacs-pretest-bug@gnu.org http://lists.gnu.org/mailman/listinfo/emacs-pretest-bug
