Oops, I misread the file. I actually think that it is correct.
IMHO, to get the tree structure, you should not follow the menu,
but only the "File:" lines.

One has

File: gnuplot.info,  Node: Terminal_types,  Next: Bugs,  Prev: Commands,  Up: 
Top

which has a single child ("Up: Terminal_types"):

File: gnuplot.info,  Node: complete_list_of_terminals,  Prev: Terminal_types,  
Up: Terminal_types

which has no children (no "Up: complete_list_of_terminals").
So the predecessor of

File: gnuplot.info,  Node: Bugs,  Next: Concept_Index,  Prev: Terminal_types,  
Up: Top

should be the last descendent of Terminal_types, which is
complete_list_of_terminals.
