revert-buffer in dired

[Dieter Faulbaum <mail@faulbaum.in-berlin.de>]

I think, it would be nice, if the newly introduced:

*** Clicking on base name of directory reverts buffer.
When 'dired-make-directory-clickable' is non-nil, clicking on the 
base
name of the directory now reverts the Dired buffer.

should not change the position of the cursor.
Is this possible?

The 'revert-buffer' in dired also changes the position of the 
cursor (to the filename of the "actual" line).
What is the idea of this?

The revert-buffer with a file doesn't do this (if the file becomes 
greater (from "outside")).
