No, I think it just attempts to give you completions for things that
look like structs.  You might want to look at generate_completion,
also in input.cc.  These completion functions are not called directly by
Octave, but by readline, when someone asks for a completion (usually
by typing TAB after entering some text).

Completion works on the symbols that are currently in the symbol table
as well as functions that might be found in files, etc.  If you have
two instances of the interpreter, you may not get the right
completions because you would be looking at a different symbol table
from the one that is being used for calculations.
