Re: dired-do-rename on "." and ".."

[Markus Rost]

   Actually, I noticed that dired-get-filename returns "." or "..",
   even if the buffer lists them as "./" or "../". So I would suggest the
   following slightly altered version of my old diff instead:

That patch seems to be an improvement.  However, what is unfortunate
with the recent changes, is that now many reasonable dired operations
don't work anymore on ".", "..", like

S runs the command dired-do-symlink
H runs the command dired-do-hardlink
M runs the command dired-do-chmod
G runs the command dired-do-chgrp
O runs the command dired-do-chown
! runs the command dired-do-shell-command

I use in fact S, M, ! on "." once in a while.  Frankly said, I prefer
to undo the recent changes instead of disabling every operation on
".".
