"Automatically revert Dired buffer on revisiting.
If t, revisiting an existing Dired buffer automatically reverts it.
If its value is a function, call this function with the directory
name as single argument and revert the buffer if it returns non-nil.
Otherwise, a message offering to revert the changed dired buffer
is displayed.
"Automatically revert Dired buffers on revisiting their directory.
This option controls whether to refresh the directory listing in a
Dired buffer when the directory that is already in some Dired buffer
is revisited by commands such as \\[dired] and \\[dired-find-file].
If the value is t, revisiting an existing Dired buffer always reverts it.
If the value is a function, it is called with the directory name as a
single argument, and the buffer is reverted if the function returns non-nil.
One such function is `dired-directory-changed-p', which returns non-nil
if the directory has been changed since it was last revisited.
Otherwise, Emacs prompts whether to revert the changed Dired buffer.
Note that this is not the same as `auto-revert-mode' that
periodically reverts at specified time intervals."
