Remove Emacs spam
My inconsistent git history-keeping is coming to bite me here. At the moment, I can only speculate about what went wrong here. The gist is this: I unintentionally committed files that were supposed to be ignored This commit removes those files which includes: - auto-save-list - elpa packages - quelpa packages - misc
