I found an obtuse unpleasantness with vi that occurs only under
unusual circumstances: If /lib/makekey and /usr/lib/makekey do
not exist, or are inexecutable, and you try vi -x or ex -x,
vi will core dump. I've fixed it for Dual, so if it sounds
worth bothering over, write me and I'll send you the fix.
