Thanks for raising this. Good findings in there.
It probably needs also review from @KeilChris and/or @ReinhardKeil to retain a common style. I am not sure if we want to add all proposed commas. Also, they can give more input on American vs British English usage.

No idea what CI is upset about this time. Merging without fixing it. Just a README update.
