The commit shown below introduced two abreast printing
for %Cpu statistics. But, the Memory & Swap lines have
always been printed on separate lines when '4' was on.
With this commit, those lines will now be treated just
like %Cpu stats, either separate lines or two abreast.
Reference(s):
. May 2020, added '4' toggle for 2 abreast
