avoid trailing spaces between app and closing }

Add a few lines of code to prevent a few spaces in some menu output.
'{$app $options}' would expand to '{app }' if no options were set.

Also, while scattered throughout, in this particular spot the
unnecessary braces around some of the variables (and not around some
others) and inside flux's braces could be very visually confusing and
lead to editing errors, so removed those.
