I don't think this is a readline vs. linenoise different...

It would be nice to consider an entire query/command to be the history entry (instead of the lines of the query). For example consider this current output:

> db.events.find(
... {timestamp: {$gte: new Date().getTime() - 10000000}}
... ).forEach(function(event)

... )

If after running that query you hit the up arrow the only thing in your history is:

> db.events.find(

It would be awesome if you could see the whole multi-line command and then be able to edit it in place.
