Interesting.  `elpa.gnu.org` is running a more recent version of Git
because the older Git crashed in this same `elpaa--get-release-revision`
in some cases :-(

Debian stable is still on Git-2.20 so it might be worth adding
a workaround in `elpaa--get-release-revision` (tho a new Debian release
is due any day now, IIUC).
