Reverting a Dired buffer centers the line that was current, and puts
the cursor at the beginning of the file name on that line.  This happens
regardless of how you revert (using `g' or using `auto-rever-mode').

For buffer reverting, you have `after-revert-hook' (and `before...'),
which you could no doubt use to counteract any such window and point
movement.
