main(): Add comment above cloned command line variables

Turns out the easiest way to share these variables between both closures
really is to clone them.

Thanks to 'durka42' on Mozilla#rust-beginners for explaining the problem
to me. In durka's words:

It's also possible to share references using Arc, but that seems more
complicated than it's worth here. Just do the copy and be done with it.
