Oliver Tappe 32c8ab89a9 * added _TabExpandedStyledWidth(), which makes sure to expand all tab chars
during the width calculation
* used _TabExpandedStyledWidth() at all places that need to expand tabs,
  fixing #4822
* removed _StyledWidthUTF8Safe() as it didn't make sense - we now perform
  the same auto-scrolling horizontally as we do vertically
