Man help page shows up for objects even if `-- --help` isn't passed

Based on my understanding of the [`_PrintResult`](https://github.com/google/python-fire/blob/master/fire/core.py#L241) function, it seems like the help page with possible methods will pop up if returning an object, even if `-- --help` isn't passed. It seems like the help page should only pop up if explicitly added.

Here is an example I came across:
I set up a fire script to connect to a sql database and run a sql file or code and return the connections cursor. Sometimes I want want to run a file creating a table or insert data without calling another method. Other times I may want to call `- fetchone` to see one row of results from a query. I don't want man pages to pop up the times where I don't call another method on the cursor, but that is what happens.
