A possible nice option for previous-sibling combinator syntax is `!+`:

    P !+ UL {
        /* UL is previous sibling of P. */

It's short (like other combinators).
it's intuitive (`!` for negation of the next-sibling combinator `+`).
it doesn't have the whitespace-around-combinator "issue".

What's important is that a responsible CSSWG member should finally (after at least 3 years after my first proposal [1]) take a _real_ action by adding a previous-sibling combinator (be it ` - `, or `!+`, or `::prev`, or anything else at first) to a real draft to prevent the proposal and the discussion results from being lost and forgotten (which is unfortunately typical here).
