Bug Description
When massaging a table I often want to restrict the content at the same time as I change the schema. For that a --where option on pt-online-
Since NibbleIterator already supports --where I think the only needed change would be to add the documentation (since the allowed options are parsed from the documentation). It works for me at least.

I can't recall off the top of my head, but I think there's a reason why we didn't include --where in the tool. It might be related to the triggers which won't respect --where. I'll leave this bug open while I think about this more.
