Multiple parser and formatter fixes for line drawing in tbl(7).
* Allow mixing vertical line bars with the layout options of the preceding layout cell. * Correctly combine box options with layout lines. * Correctly print vertical lines in data rows, with the right spacing. * Correctly print cross markers and left and right ends of horizontal lines even if vertical lines differ above and below. * Avoid the bogus error message "no table data cells" when a table data section starts with a horizontal line. No increase in code size.
