When you do a --dry-run it won't create directories.
This means that --dry-run won't work if the destination
directory doesn't exist.  I'm sure you control whether or
not the destination directory exists.

If the real destination is empty or non-existant doing a
--dry-run with the eventual link-dest directory as the
destination will yield the list of what has changed.
