It seems like tab completion does not work when one of the options has a help field? ``` import click from click_repl import register_repl @click.group() def cli(): pass @cli.command() @click.option('--test', default=1, show_default=True, help='Test help') def hello(test): click.echo("Hello world!") register_repl(cli) cli() ``` Option test does not show up in tab completion, but when the `help='Test help'` is removed it will show up. Is this a bug?
