I think this is a good thing to do for non-transient mark mode.

So to ignore the existing mark and to use the directory in the next window
(if dired-dwim-target=t) there will be different methods:

- in non-transient mark mode: set the mark on the current line;

- in transient mark mode: deactivate the mark.

However, I'm not sure what to do in transient mark mode with
mark-even-if-inactive=t.  Is it expected that with the inactive mark
dired-diff should try to use the directory from the next window?
