SCI_AUTOCSHOW documentation doesn't seem to mention anything about this index
Well its an implementation detail internal to Scintilla, nothing the user sees, so no need to mention it here.
It only relates to the value set by the `SCI_AUTOCSETORDER` function, so thats where its mentioned.
I just put `SSM(sci, SCI_AUTOCSETORDER, 2, 0);` before the call to `SCI_AUTOSHOW` at editor.c:604 and it indeed seemed to fix the problem.
