Client: Write() shouldn't allow a write without a single parameter

[d2g]

Currently you can call the write function on the client without any parameters.
i.e.
c, err := client.NewClient(config)
if err != nil {
t.Fatalf("unexpected error. expected %v, actual %v", nil, err)
}

_, err = c.Write()
if err == nil {
    t.Fatalf("unexpected error.  expected %v, actual %v", nil, err)
}

will not error

I can' think of an instance where you would want to allow zero writes.

Can I suggest the function is changed to:
func (c _Client) Write(w Write, ws ...Write) (_Results, error)

I think the signature is fine, but we should check for len(writes) > 0 and if not, throw an error.

It looks like this was fixed in #1868. I'm closing this since it doesn't seem to be relevant anymore. Please reopen if this is still an issue. Thanks.
