From 32793298b76c6e6c3858e98b2d4ef9aed8f30eb3 Mon Sep 17 00:00:00 2001 From: Vincent Ambo Date: Wed, 14 Apr 2021 00:19:22 +0200 Subject: chore(3p/emacs): Remove obsolete third-party packages We don't need these in the depot anymore as the Emacs overlay now provides newer versions of them, or because they are not used anymore.
