I noticed a probably unintended behavior in help() usage:

when an output is set on pydoc.Helper(), most of its methods
use this output instead of a pager.
But 'True', 'False' and 'None' as well as all topics, keywords
and symbols always use a pager instead of the configured output.

My use case is to use the pydoc help system to display help contents
in Geany (a text editor) in a graphical manner
(and so I cannot make any use of a pager).

Example code:

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

from io import StringIO
import pydoc
import sys

if __name__ == '__main__':
    help_text = StringIO()

    helper = pydoc.Helper(output=help_text)
    # help contents are written to help_text as expected'pydoc')

    # the following calls each show the help contents in a pager instead
    # of using the configured output'True')'False')'None')'**')  # symbol example'SEQUENCES')  # topic example'await')  # keyword example

Tested against Python 3.7.3.
