   When I try to enter the appended table definition
I get "Failed assertion..." message from the gtbl. If
I change the lines "c s c s c s" into "c c c c c c",
all goes fine, except the output is not quite what I
want (yes, I'm trying to draw a simple tree structure
with tbl -- just learning things, not ready to dig
into "pic" just for this simple thing, which should be
possible to do with tbl). [maybe I don't understand
tbl yet, so if this is an obvious thing, reply with
mail, also I'm a bit uncertain how to count TABS
on those lines that have "s", but I have tried all
variations, gtbl seems to barf before it gets to
the data lines].

groff -t -ms tbltest.txt > test.tmp
gtbl: Failed assertion at line 1237, file `table.c'.
