I suppose node.dimensions produces an hlist, since you can't choose 
between h- or vmode to build the list, and it works perfectly well 
horizontally.

And I suppose the "vlist" in

node.dimensions(<head's glue specs>, vlist)


doesn't make sense; a list of node isn't vertical or horizontal, it 
simply occurs in a vertical or horizontal container (... unfortunately 
also called a list). But I might be completely wrong.

Anyway it'd be nice indeed to have a switch for node.dimensions which 
measure either vertically or horizontally.

Best,
