Tiny esthetic changes to Documentation/laptop-mode.txt

Here's a tiny patch making a few esthetic changes to
Documentation/laptop-mode.txt
To me this patch makes sense, but feel free to disagree, I don't feel
strongly about it at all.

It changes a single URL to its strictly correct form (directories should
end in /), and it makes the arguments to main in an included example
program follow convention and be named argc and argv.
