Kerno does not appear to have this. In the World, Talarian possibly
does (it's a known areal feature). I know the Daine languages have
largeish and complex deixis tables, not just in space but also in
time, in relation and quality.
I don't have the actual vocabulary, though, and the concepts are not
entirely clear to me.
