bin/mailman command hangs
I ran into this when testing for !417 (merged). The issue is that bin/mailman
with no subcommand or bin/mailman help
but not bin/mailman --help
produce the appropriate output but then hang instead of exiting back to a command prompt. This occurs in the tox virtualenvs with Click 7.0 on my local machine. It causes the test test_mailman_command_without_subcommand_prints_help
in mailman/bin/tests/test_mailman.py
to hang. This doesn't occur on my local machine with Click 6.7 and it doesn't occur with Click 7.0 in CI on gitlab
