Fix when the --format flag prints a new line at the end

If the output is to a terminal, return a new line at the end of the
output so that the output is visually appealing. If the output is being
piped, or saved to a file, basically not being outputted to a terminal, do
not print a new line at the end of the output. This ensures any further data
manipulation with the results happens smoothly without requiring to remember
the '/n' at the end of the output.
