This formatting is needed in the optimized table formatting algorithm for shrinking the current table line to try the best to avoid re-formatting the whole table. However, this breaks cursor motion and may also affect other table related behaviors. The fix is to move this formatting to get_aligned_rows(). Now table rows are not affected by any means, because the current row is only replaced temporarily for the formatting purpose only and gets reverted as soon as the check is finished. Fixes #656.
