Fix update_lines performance issues

This resolves performance issues with the `update_lines` method that
were caused by excessive updates without underlines or strikeout
present.

This also resolves a bug that was causing the underline and strikeout to
extend beyond the end of line in some rare cases.

This fixes #114.
