+Log Message:
+-----------
+Set the maximum column index in a tbl(7) to the maximum *right* edge
+of any cell span, not to the maximum *left* edge, which may be smaller
+if the last column of the table is only reached by horizontal spans,
+but not by any regular cell in any row of the table.
+Otherwise, the algorithm calculating column widths accessed memomy
+after the end of the colwidth[] array, while it was trying to handle
+the rightmost column(s).
+
+Crash reported by Jason Thorpe <thorpej at NetBSD>
+via https://gnats.netbsd.org/cgi-bin/query-pr-single.pl?number=54069
+and via Thomas Klausner (wiz@).
+Christos@ Zoulas sent a (correct, but slightly confusing) patch.
+The patch i'm committing here is easier to understand.
