DBQuery.shellBatchSize is deprecated and not used for this, unlike the issue description states.

The documentation for the old shell states that cursor.batchSize() does not control the output display size in the shell. That is no longer true: It does control the output display size (in addition to also setting the driver batchSize), and it is the only thing that does that.

As a user,
I want to control the batch size when I issue my queries and aggregations
So that I can customize it to my needs and my screen size

It's possible to set DBQuery.shellBatchSize to control the batch size for queries and aggregations (default is 20)
When a query or an aggregation returns more than DBQuery.shellBatchSize results, results are paginated and each page includes at most DBQuery.shellBatchSize results
When there are more pages of results to see, the shell prints Type "it" for more
It should not be possible to delete DBQuery.shellBatchSize
