test.m: Overhaul function (also fixes bug #39703). * test.m: Rewrite docstring. Use more meaningful variable names. Run in batch mode if an output argument is requested (bug #39703). Change verbose to -1,0,1 three-level indicator to match "quiet", "normal", "verbose". Change all boolean type variables to true/false rather than double(1)/double(0). Return a boolean pass/fail variable if only one output is requested rather than a double. Remove duplicate subfunction bundle, replace with var2struct. Add many more built-in tests. * aspell-octave.en.pws: Add new words to Octave custom spellcheck dictionary.
