  Log Message:
  -----------
  [pseudo] Fix bugs/inconsistencies in forest dump.

- when printing a shared node for the second time, don't print its children
  (This keeps output proportional to the size of the structure)
- when printing a shared node for the second time, print its type only, not rule
  (for consistency with above: don't dump details of nodes twice)
- don't abbreviate shared nodes, to ensure we can prune the tree there
