Hi Jérémy,

Thanks for the update and for clarifying the license with the author.

This has a trivial conflict with master (4a0399e277 at the time I
applied it for testing).  That'd be easy for whoever eventually commits
your patch to clean up, but, if you resend the patch for the other
reasons I mention below, it'd be good to resolve it on your end by
moving that to a newer base.

You should specify a `file-name' so that the directory in the store
contains the package name.  Note that you can run `guix lint' to catch
issues like these:

  $ pre-inst-env guix lint emacs-ac-geiser
  gnu/packages/emacs-xyz.scm:21842:5: emacs-ac-geiser@0.1: the source
  file name should contain the package name

This commit is a couple of commits after the v0.1 tag, so you can
represent that with something like

  (let ((commit "abcdef...")
        (revision "0"))
    (package
      ...
      (version (git-version "0.1" revision commit))
      (source
       (origin
         (uri (git-reference
               (url "https://github.com/xiaohanyu/ac-geiser.git";)
               (commit "abcdef...")))

You can find a good number of examples in emacs-xyz.scm.

Because the author clarified the license in the next commit
(93818c936ee7e2f1ba1b315578bde363a7d43d05), I think that'd be a good
commit to use.

Formatting/consistency nit: Most packages put "(base32 ..." on a new
line.  I think the same is true, to a lesser extent, for the value of
propagated-inputs below.

Thanks!
