dired-undo undoes dired-undo

[Chong Yidong]

C-x C-f RET   (visit your home directory in Dired)
m
m             (mark the first two files in Dired)
C-_           (dired-undo unmarks the second file)
C-_           (dired-undo remarks the second file -- wrong!)

The second invocation of dired-undo should unmark the first file.
Emacs 21.3 behaved properly, so this is a regression.
