Implement tbl(7) lines in -T html output,
as far as they are on the edges of table cells rather than going through the middle of cells: * the box, doublebox, and allbox options; * the | and || layout modifiers; * and the _ and = data lines; - but not yet _ and = in individual layout and data cells. Missing feature reported by Pali dot Rohar at gmail dot com.
