By the way, here is a simple way to test Magit without installing it in your
Emacs. However, you will need Eldev (external relative to Emacs).

1. Install Eldev (https://github.com/doublep/eldev#installation)

2. Check out Magit sources, e.g. to `~/git/magit'

3. Run `$ cd ~/git/magit/*lisp*' (I don't know why they have this layout)

4. Create file `Eldev-local' with the following contents (since the
project doesn't use Eldev, you have to do this manually):

(setf eldev-project-main-file "magit.el")
(eldev-use-package-archive 'gnu-elpa)
(eldev-use-package-archive 'melpa)

5. Run e.g. like this: `$ eldev emacs --eval "(magit-status-setup-buffer
\"~/emacs\")" ',
assuming `~/emacs' is a Git checkout you work on.
