Most lines are like 20-30 characters wide, no matter the limit. So the wasted space will be almost the same, no matter the limit. On the other hand with 120 limit every once in a while you have to read very long line, and with merge tools or big fonts you can have problems and have to scroll. IMHO it's not worth it. 80 is ok.
