DELETE doc without rev

Hi,

I would like to delete a document from DB. But for this purpose I need 
to explicitly mentioned a version, what's assume, to get
one more call for get it.
Is there any way to delete doc without mentioned revision of doc, e.g.

$ curl -X DELETE http://localhost:5984/mydb/mydoc-123

Thanks,

I find it helpful to use doc._rev as the value in emit()s that would
otherwise have a null, in views you might query to identify documents
to delete.

For quick manual removal from the command line, I  use this bash
function to automatically fill in the rev:

rmdoc() {
    local url
    for url in "$@"; do
        curl -X DELETE "$url"?rev="$(curl -I "$url" | sed -ne
's/^Etag: "\(.*\)".*$/\1/p')"
    done
}

e.g.

rmdoc http://localhost:5984/mydb/mydoc-123

You must provide the current _rev to delete a document. However, you
can get the doc's current rev from the ETag in a HEAD response.

$ curl http://localhost:5984/mydb/mydoc-123 -I
HTTP/1.1 200 OK
Server: CouchDB/1.0.1 (Erlang OTP/R13B)
Etag: "3-825cb35de44c433bfb2df415563a19de"
