;; PERF: Stop copying the selection to the clipboard each time the cursor
;; moves in visual mode. Why? Because on most non-X systems (and in terminals
;; with clipboard plugins like xclip.el active), Emacs will spin up a new
;; process to communicate with the clipboard for each movement. On Windows,
;; older versions of macOS (pre-vfork), and Waylang (without pgtk), this is
;; super expensive and can lead to freezing and/or zombie processes.
;;
;; UX: It also clobbers clipboard managers (see emacs-evil/evil#336).
