This doesn't fix the problem. If it's a newbie, they should be given Nano. They probably just want to get the job done, whatever it may be. It shouldn't be assumed that now is the time for them to learn Vim (which is no small thing). Neither should it be assumed that quitting Vim solves the problem. They might not know how to reconfigure the default editor that some other program is using, for instance.
