I saw the change to the code as a band-aid, which wouldn't have been
necessary if we had the missing refs/ entry.  Fully populating the
leading levels explicitly may give the application more flexibility
by yielding results different from hardcoded -1 like the patched
code gives.  

But perhaps treating a path that matches a missing intermediate
level just like a path that did not match anything in the trie is
what we want anyway, so I guess the code change was the right thing
(as opposed to a band-aid).

Thanks.
