By kmullin:

Actually tail -f is a good example of this. It does exit with status 130, but also doesn't really mean much... "an exit status of zero indicates success, and a nonzero value indicates failure"

If I control-c from tail -f, IMO its not a failure that the program was interrupted, but rather, a successful termination, initiated by the user.
