So much whining on this thread...
Want to quit vim? How's about:
1- Hit ctrl-z
2- Type "kill -9 %"
3- Hit enter
Result: dead vim. Heck, dead anything that was previously on the foreground.
This works with emacs, vi, nano, and, I guess pretty much everything, since ctrl-z is captured by the shell and never gets sent to the application (I think).
