In Mongo, how do I pretty-print results so .find() looks like .findOne()

It may not have been available at the time the question was asked, but to make the default output for all find() queries to be pretty, I use:

DBQuery.prototype._prettyShell = true

I also add the following:

DBQuery.prototype.ugly = function() {
    this._prettyShell = false;
    return this;
}

which enables me to uglify the results of a single find() query using:

db.mycollection.find().ugly()

I typically add both prototype declarations into my ~/.mongorc.js file so they are available in all mongo cli shells.
