Everything Tassilo said seems correct to me, too.

Even if they are not aware, they won't lose anything, do they? They will
also probably pick it up easily enough (I learned this after I observed
"inconsistent" behavior in rsync.).

I have attached a new patch that adds a custom option. While I do like
having the option, IMO it should be on by default.

I think we can add an `'ask' choice to this custom variable I introduced in
this patch, but that really seems like overkill to me; You can just set
`dired-create-destination-dirs' to `'ask', and if you refuse to create the
new directory, you will still have your previous behavior: `old_name` ->
`new_name/` -> user refuses dired' prompt to create a new directory ->
fired moves `old_name` -> `new_name`
