It could be that the order of the marked files changed after reverting.

But even if not: if you look at the use of the variable `next-position'
in `dired-map-over-marks', it is also possible to get such an effect if
the line lengths change.

So the command `dired-do-compress' is not robust against this effect.
Other commands calculate the complete list of marked files first,
`dired-do-chxxx' and `dired-do-chmod' for example.  So I think it is not
unavoidable that it is like that.


Michael.
