--delete and --dirs

[Guillaume Etorre]

rsync-2.6.6 manpage says:

       --delete
[...]
              This option has no effect unless directory recursion is enabled.


True. In fact, I noted that --delete doesn't delete anything if --dirs 
is used rather than --recursive.

Is there any reason for --delete not to delete when used with --dirs?
Is there a way to get rsync to actually delete files on the receiving 
end when using --delete with --dirs?

Thanks for any help.
