Document that default should be a tuple when used with the multiple flag

See original GitHub issue

If a choice option also allows multiple values, the default value is split into single chars and no longer matches one of the choices.

The desired behavior is to specify multiple format options and have each one of them validated against the choice options available. The default value can be one of the choice options.

choice option allows multiple values, with a default

@click.option('--format',
              default='one',
              multiple=True,
              show_default=True,
              type=click.Choice(["one", "two"]),

error

Error: Invalid value for "--format": invalid choice: o. (choose from one, two)
