After googling for a while, I finally stumbled across an old Python 2
example that pointed me in the right direction. Here's the sort of
example I had hoped to find in the module's docs:

#!/usr/bin/python
import readline

readline.parse_and_bind('set editing-mode emacs')

while True:
    try:
        line = input('enter something (EOF to quit): ')
    except EOFError:
        print()
        break
    print('You entered: "%s"' % line)
