[csswg-drafts] Pull Request: [css-backgrounds] list entries not empty

ewilligers has just submitted a new pull request for https://github.com/w3c/csswg-drafts:

== [css-backgrounds] list entries not empty ==
The entries in background-position-x and background-position-y
may not be empty.

We use the exclamation point (!) modifier to indicate that
a keyword or length-percentage (or both) must be present,
they cannot both be omitted.


See https://github.com/w3c/csswg-drafts/pull/3904
