annotate libinterp/corefcn/error.cc @ 28268:7eddf9608d61

Pretty print warning() output state when nargout==0 (bug #58296). * error.cc (display_warning_options): Add column headers "State" and "Warning ID" to printed table of warnings. * error.cc (Fwarning): If operation is "query" and nargout == 0, pretty print "all" warnings with display_warning_options() or construct a status message and display on octave_stdout.
