Some cleanup and no longer depend on loop

[tarsius]

Two years ago, in #21, I experimented with using magit-section.el in this package. Recently I released that library as separate package, so I picked that experiment up again. If nothing else it might serve as an example for how to use magit-section in a package that isn't Magit.

Anyway, I did some cleanup while working on that and now propose those changes using this this pull request.

I am aware that you are the author of loop but I still think you should avoid depending on an additional package just to make a single function slightly less more readable.

Thanks!

Yeah, loop.el taught me a lot about writing and testing elisp macros. I almost never find myself needing it in practice though, so I agree the code is better here without it.

You are welcome!
