annotate libinterp/corefcn/interpreter.cc @ 23819:5d8ef9b859f8

defer execution of user code to interpreter::execute (bug #51631) * interpreter.cc, interpreter.h (interpreter::execute) Execute startup files, eval option code, and command-line scripts here instead of in interpreter::initialize. (interpreter::initialize): Don't return anything. Change all uses. * octave.cc, octave.h (application::ininitialize_interpreter): Don't return anything. Change all uses. * main-window.cc (octave_interpreter::execute): Don't get exit_status from interpreter::initialize.
