It would be really nice if I could do:

```javascript
var seq;

var f = follow(url)
f.since = -2
f.on('change', function (info) {
seq = info.seq
})
```

So, -1 would actually be since=currentSequence. And -2 would be since (currentSequence - 1). That way, I could use -2 and as soon as the feed connects i'll get my global for the current sequence back.
