# A boxed, unkept table that overruns the page bottom will produce ugly
# output; it looks especially bizarre in nroff mode.
#
# We set the page length to 2v to force a problem (any boxed table in
# nroff mode needs 3 vees minimum), and put a page break at the start to
# catch an incorrectly initialized starting page number for the table.
