[csswg-drafts] [css-grid] Not clear how to read the <name-repeat> dfn

tidoust has just created a new issue for https://github.com/w3c/csswg-drafts:

== [css-grid] Not clear how to read the <name-repeat> dfn ==
The [`<name-repeat>` definition](https://drafts.csswg.org/css-grid-2/#typedef-name-repeat) is currently set to `repeat( [  | auto-fill ], +)`.

I'm not clear how to interpret that value:
- Does `[ | auto-fill ]` mean an empty value is allowed?
- What does the `+` apply to? Shouldn't the definition use `#` (and drop the comma)?
