octave: libinterp/corefcn/interpreter.cc annotate

annotate libinterp/corefcn/interpreter.cc @ 23100:a40e586b66ba

eliminate global variable reading_startup_message_printed * parse.h, oct-parse.in.yy (reading_startup_message_printed): Delete global variable and all uses. * interpreter.cc (interpreter::execute_internal): Use verbose option flag instead of reading_startup_message_printed to decide whether to display newline after reading startup files.
