It's an extremely annoying misfeature in ksh. If $EDITOR starts with the letters "vi" then it defaults to vi-style command line editing. You can use "set -o emacs" to override that, but then if you sudo/doas to root it will reset to vi-style editing because of the exported EDITOR variable. On some machines I got fed up enough with this to symlink "emacs-notreally" to vim and set EDITOR=emacs-notreally...
