Ah, I even didn't know there is something like nametrans. That indeed is
not 1:1 mapping.

Good points. If there will be reverse_nametrans, we can pass given
folder name through nametrans and then by reverse_nametrans to make sure
we got back to initial name. Bail out when nametrans is used sounds like
a good start.
