From 1e982599c7f339de5711a30d937e9f4ab18a529f Mon Sep 17 00:00:00 2001

Subject: Plug in the "head" concept for tables.  A tbl_head specifies the full
 layout for each row, including vertical spacers.  One grabs the tbl_head for
 a row and iterates through each entry, plugging data from the tbl_span into
 the header as appropriate.

This is pulled in more or less verbatim from tbl.bsd.lv.  In fact, this
is verbatim except that lists macros are made into hard-coded lists (for
compatibility, as long-ago noted by joerg@).
