Nack. This patch is pointless, the DT_REF lexing will already resolve paths in the form &{/some/path} and I see no reason that won't work for tree merging as well. Oh, and bare &/path/to/node is a bad idea anyway, more about that later. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.
