What is the difference between the values for `--guard-else`?

[rgoldberg]

What is the difference between the values (?

Many descriptions of option values are vague.

What are the differences between the following values?

--call-site-paren   balanced, default
--closing-paren     balanced, default
--guard-else        next-line, auto
--smart-tabs        enabled,disabled
--xcode-indentation enabled,disabled

Is there a better place to ask usage questions than here in GitHub issues?

Thanks.
