DOC: Documentation of passing multiple values in "option" vs "argument" isn't sufficiently explicit

Issue Content

I was looking into passing multiple (N>=1, all N >=1 allowed) white space separated values via an option.

This does not seem possible at the moment, but the documentation wasn't very clear. It's only possible to pass an exact number of space separated values via an option, but not a list: https://typer.tiangolo.com/tutorial/multiple-values/options-with-multiple-values/

Multiple values are only possible via argument, yet the documentation for the two types reads almost identical (at least the first few paragraphs): https://typer.tiangolo.com/tutorial/multiple-values/arguments-with-multiple-values/

It would be good to be precise in the first paragraph about the fact that options don't allow you to pass N>=1 values.

Maybe one could accept multiple values by specifying a separator that's not white space, like comma-separated - but that's a feature request in a bit different direction.

I just encountered this issue too. This is definitely a feature I'd absolutely love to have (white space or comma separated lists)

I'm really not a fan of having to re-write the commands like --command val1 --command val2

Either

--command val1 val2 or --command val1,val2 would be such a big feature for me.

Not sure where to put in a request for this, or if its been stated that it is not going to be implemented!

Thanks so much to all contributers of this repo anyhow, found it a few days ago and switched all my CLI workflows to it almost immediately! Love it!
