Description
Given that we state the syntax:
{ upsert: <Boolean>,
multi: <Boolean>
}
and then also specify the 2.2 syntax
{ <query>, <update>, <upsert>, <multi> }then when we state that upsert can be either a Document or a Boolean, which is kind of confusing since it seems to suggest
{ upsert: <document> }which is nonsensical for either the latest syntax or the 2.2 syntax. Ditto with multi.
