util: fix default termwidth() under Windows sys.stdout.write('-'*80 + '\n') or sys.stdout.write('-'*80 + '\r') do not work on Windows as they do on unix. On a 80 columns Windows console, the extra CR or LF are interpreted as if belonging to the next line, so the first command displays 2 lines (only one on unix) and the second one leave the line visible and move back to the following line. To avoid this, we sacrifice one column under Windows.
