Hm, I remember we worked on this feature ages ago but I don't recall exactly
where we ended up on this.

The --range option only changes the range the request asks the server to
deliver in its response (the Range: header). The header that limits what parts
you send in a PUT would be Content-Range: (AFAIU), and you should be able to
set that manually if the receive just understands it.

I don't think we have any option that allows you to do this conveniently.
