Yes, of course. It's just that I thought that Albert was building its own
Emacs, so I wanted to know if he were doing something different. But it's
an "official" snapshot.

And a recent one, in fact. The commit is dated 2019-06-04, but that's
because of some merge. The previous commit is indeed from 2019-09-18.
