Fix some minor issues

- in the OASSIGN of the roper, i=0 means variable is _found_ as the
  first one in the scope, so it should be freed
- in the rwith, nwith is stored by the node, not mod (affects only
  printing of the "s", though, lol)
- in add{edge,prop} target is ulong, so check >=0 is redundant
