These commands are only enabled when the hush shell is enabled and can
be useful in scripts such as:
while true do
echo "Booting OS...";
run $bootcmd;
echo "Booting OS failed";
sleep 10;
done

This could be added as a hush builtin command if people don't want to
pollute the top-level help listing. Its debatable if 'false' should
be added also, but I threw it in to be consistent.
