From 80f6fa645b8fb17f3cb7524cefc92cdc4d445dfd Mon Sep 17 00:00:00 2001
From: Ingo Schwarze <schwarze@openbsd.org>

Subject: Multiple tbl(7) improvements: * Do not discard data that lacks a
 matching layout cell but remains within the number of columns of the table as
 a whole. * Do not insert dummy data rows for any layout row starting with a
 horizontal line, but only for layout rows that would discard all the data on
 a matching non-empty data row. * Print horizontal lines specified in the
 layout even if there is no matching data cell. * Improve the logic for
 extending vertical lines to adjacent rows, for choosing cross marks versus
 line segments, and some related details.
