I just realised this is wrong. One can do:

 <extern|coq-prompt-colour|>

and then coq-prompt-colour gets as argument a _tree_ that is exactly
at the position the value node was in my previous scenario. So it just
has to do a "tree->path" and bingo, same result. I take my patch back,
simpler/better solution found.
