It's certainly not always there on MS Windows. Even though vi is on my 
Linux system, if it were to suddenly be executed for me, it would take 
me several minutes just to figure out how to close it. For people who 
don't know vi, it is extremely confusing.

Any "default" editor would need to have visible online help so people 
unfamiliar with it wouldn't get stuck. That also rules out emacs. Nano 
would be an friendly option, but I'm not sure how widespread it is 
outside of gentoo.

But I think we can do better than just bringing up a nice error that 
explains exactly how the user can configure their system to use the 
editor of their choice. Since we're going interactive at that point 
anyway, why not allow them to enter the name of their editor right then, 
and offer to save that choice for them (if it worked). Or maybe don't 
even ask, and just save it and tell them how to unset it.
