I agree that your statement is true, but it is still not quite self sufficient.
For the time being I have no idea how to make it easier to be understood. As I have said, for me it is a little confusing.
I would pay attention to Kirk Parker <khp@equatoria.us> idea: when_clause [ when_clause [...]] to indicate repetitions without commas and xyz [, xyz[, ...]] to indicate repetitions that require commas.
I'll be back if some worthy idea will hit my mind.
Best regards, Cristi Boboc

Hello!Thank you. I was fooled by the fact that sometimes it is marked with [...] and other times with [,...]
I think that consistency might worth attention, since [...] may indicate "anything", while [,...] are more likely to indicate a specific thing that may be repeated.
That isn't how that works. The former means you don't have to add a comma between each of the multiples, the later means you do.
